SPSS is a data science and analysis utensil constructed by means of IBM. in case you’re the consume of SPSS, listed below are some explanations to elect Db2 as a backend database to your initiatives.1. It’s free
SPSS is frequently used via students or impartial consultants. And so, you may also like free things in case you consume SPSS. The Db2 on Cloud Lite pass is free. no longer simply free for 1 year, like some other databases out there. It’s free always. despite the fact, you’ll deserve to reactivate your free tier every 30 days, so that they will retain resources open for others.2. It’s measure to run, however..
You don’t necessity to exist a DBA to consume Db2 on Cloud. Db2 on Cloud is utterly managed. seat of attention on statistics science, and not running databases.
youngsters, I may soundless point out that the setup system for Db2 on Cloud with SPSS may exist a bit longer. however, once you accomplish installation the database connection, managing your database should exist fundamental. perquisite here’s a video on YouTube which walks through establishing Db2 with SPSS on windows that could exist constructive.
Having main issue? Don’t exist a stranger! achieve out to me in the feedback below and that i’ll assist procure you begun.3. Scale on-demand
if you are able for a paid plan, you could elect Flex. From there, you only necessity to pay for what you use. that you may scale up and down the usage of sliderbars. So, which you could scale up to flee your analysis, and then scale lower back down. if you would like much more vigor, elect a notice at Db2 Warehouse on Cloud. Its big parallel processing engine (MPP) can dissect terabytes of statistics sum of a sudden.four. dissect as much as 100X quicker with BLU in-reminiscence acceleration
IBM’s BLU acceleration is a massive talents over the open source options nowadays. It uses in-reminiscence columnar expertise to research information lots faster. The BLU engine makes consume of lots of other patented IBM speedups, like actionable compression. That allows you to query statistics whereas it’s compressed, which each saves compute time from decompression and maximizes RAM for a double-whammy of energy.

DBI software, a issuer of Db2 LUW efficiency options, has brought recent capabilities in its pureFeat V7 performance management Suite for IBM Db2 LUW.
With this liberate, DBI is elevating efficiency monitoring to support DBAs and management teams to elect supervision of the volatility of agile environments, stated Scott Hayes, president and founding father of DBI.
Agentless colour option - IBM has carried out a lot of travail in the newest unencumber of Db2 (edition 11) to acquire pureScale more straightforward to acquire consume of, result into effect, and administer and, as a result, DBI has seen better adoption of pureScale over the final one year, said Hayes. To aid consumers procure extra from pureScale, DBI’s newest release provides effective Db2 pureScale performance reporting and trending, including recent performance displays for global Bufferpools, CF Wait instances, CF Processing instances, the Cluster Facility, and Member efficiency.
Agentless Collector option - besides DBI's agent-based mostly collector, the unlock adds a brand recent agentless collector option for monitoring cloud databases the position a server login instant is not accessible. The agentless collector makes it more convenient to computer screen assorted databases with minimal overhead and administration and is specially censorious for monitoring cloud databases however additionally for convenience in light-weight monitoring of non-critical databases, referred to Hayes.
Database ranking Calculations - in keeping with DBI, many valued clientele admire that the database ranking provided by using pureFeat helps them perquisite now triage databases to seat of attention on the worst complications first. The rating, starting from 0-10,000, is cost based mostly, helping DBA groups to find hidden or emerging future complications.
prior to now, the "analyze database rating" duty highlighted complications and offered suggestions for resolution, but there changed into no indicator for the severity of the complications recognized. The remarks from purchasers, observed Hayes, become that they preferred the utensil nonetheless it was now not pellucid what the worst complications Enjoy been.
in the recent unlock, the variety of facets subtracted for each issue is printed so that DBAs can elect note what the worst problems are.
"Index Design Workbench" - DBI’s Predictive Index influence evaluation (PIIA) helps Db2 users exist mindful the Enjoy an repercussion on of including recent indexes given SQL workloads for any timeframe, helping DBA teams to tune Db2 databases with self assurance and also helping them benefit change exploit approvals extra readily.
building on the success of this capability, the brand recent unlock adds the competence for DBAs to regulate indexes suggested with the aid of the Design consultant (add, procure rid of, or reorder columns, and alter style sequences) or invent their personal recent index that will also exist handed into the affect evaluation.
Now, valued clientele Enjoy the capability to remove columns in a recommended index or reorder columns, and in the event that they feel they're smarter than the software, spoke of Hayes, they could create their personal index and result it through the predictive repercussion analysis utensil to peer if it will even Enjoy the a advantageous option repercussion that they expect.
greater trend Charts - probably the most favorite capabilities offered with the aid of DBI is the fashion charts with exchange event indications plotted on them. youngsters, prior to now, it turned into best feasible to graph unavoidable similarly scaled metrics across time on an X and Y axis. during this free up, a recent Z axis option has been added, making it workable to graph assorted metrics across time, assisting to establish trigger and impact.
for instance, DBAs can now graph the medium transaction response time together with the number of latest and lively database connections. A DBA might survey that after the database is operating 30 concurrent energetic connections, response instances birth to late down, stated Hayes.
The want for speed
With the improved seat of attention on DevOps, there is further pressure to elect changes straight away and that creates travail and stress for DBA groups, accompanied Hayes, pointing out that “exchange is an invitation for brand recent issues.” through featuring the recent capabilities in this unencumber, he mentioned, DBI is offering people with extra insight into what is occurring inside their Db2 environments.For extra suggestions, goto www.dbisoftware.com/pureFeat-70-DB2-LUW-efficiency-tools.phpand DBI utility pureFeat V7 information.
newsIBM DB2 Will target Oracle Database developers
IBM this week introduced a recent version of its flagship DB2 database with utility with the objective to provide compatibility with functions developed for Oracle databases.
Embedded in IBM's imminent DB2 9.7, code-named "Cobra" and slated for unlock in June, is application that gives compatibility with EnterpriseDB Corp.'s Postgres Plus advanced Server database, which helps sum Oracle statistics kinds, SQL syntax, semantics and different functions developed with Oracle PL/SQL kept processes. Postgres superior Server is constructed on the open supply PostgreSQL database.
"The set of applied sciences they Enjoy introduced will aid builders of custom applications and packaged functions installation to DB2," spoke of Bernie Spang, director of approach, analytics and records management for IBM's utility community.
For IBM, or not it's the first time the enterprise has licensed expertise from a company of open source database software, even though EnterpriseDB founder Andy Astor spoke of the software embedded in DB2 is in keeping with proprietary code.
"here's no longer an open supply play," Astor observed. "every thing else they accomplish is open supply however that is one of the techniques they acquire their cash, by using selling that compatibility know-how both to carriers like IBM, in this case, and to clients within the character of Postgres Plus advanced Server."
EnterpriseDB elements to a yoke of shoppers including FTD and Sony on-line leisure which Enjoy migrated applications developed for Oracle databases to Postgres Plus. The elect supervision of IBM "gives them with proven performance for enabling compatibility between DB2 and functions written for Oracle," mentioned 451 community analyst Matthew Aslett in an email.
"Database migrations are complicated, time-drinking, costly and infrequent, so any performance that makes the manner less difficult is going to exist welcomed by pass of those businesses that are prepared to acquire the soar," he added.
The licensing pact is the primary by EnterpriseDB, but Astor talked about others are being negotiated.
IBM is hoping the circulate will inspire greater customers to migrate to its InfoSphere Warehouse 9.7 enterprise version, a knowledge-cleaning and company analytics platform in response to DB2 and expertise IBM bought from Cognos.
the recent release is centered at bringing statistics mining, analytics and cubing to departments of organisations and smaller corporations, Spang observed. additionally recent in DB2 is aid for performing simultaneous transactions throughout XML and relational statistics.

DB2 provides a variety of options for connecting to other DB2 and non-DB2 data servers:
DB2 Connect™—This add-on product provides support for applications executing on Linux, UNIX, and Windows to transparently access DB2 data servers on i5/OS, VM/VSE, and z/OS environments. DB2 Connect provides much more than just connectivity; more details of its capabilities are provided later in this chapter.
DB2 Replication—This feature provides replication capabilities for DB2 data servers. There are two kinds of replication, SQL-based replication and Queue-based replication (also know as Q-replication). Both are sometimes referred to as Data Propagator (DPROPR).
SQL-based replication is included in sum of the DB2 mainstream editions that flee on Linux, UNIX, and Windows. It's made up of two components, CAPTURE and APPLY. It uses SQL to replay data on target servers.
Q-Replication is built on the IBM WebSphere MQSeries® technology and is generally thought to exist a more available and powerful replication technology. You can add this capability to a DB2 environment through one of the WebSphere Information Integrator products.
Once a DB2 application has been developed, you necessity to install connectivity software on each client workstation in a two-tier environment. If you are deploying a Web-based application in a three-tier environment, you necessity to, at a minimum, install the DB2 client connectivity software on the application server. In DB2 9 there are basically two types of clients, the DB2 Runtime Client and the DB2 Client.
A DB2 Runtime Client provides the minimum client footprint (about 20–30 MB) to support connectivity to DB2 9 data servers (the exception to this is if you elect to support communication via specific API drivers, covered later in this section). When you install a DB2 Runtime Client, you install a driver to support sum the common programming methodologies, including ADO.NET, ADO, OLE DB, ODBC, JDBC, SQLJ, static SQL, and more.
Using a DB2 Runtime Client you can accomplish basic functions, such as running any DB2 commands or SQL statements from a DB2 CLP or CLP session; however, for the most part, this client comes with no other capabilities than supporting data connectivity. For example, there are no graphical-based management tools, documentation, and so on. You can download a DB2 Runtime Client at www14.software.ibm.com/webapp/iwm/web/preLogin.do?lang=en_US&source=swg-dm-db2rtcl.
A special DB2 Runtime Client is made available as Windows Merge Modules (.msi files), which makes the installation of this software within Windows applications more natural. You can download these files at http://www-304.ibm.com/jct03002c/software/data/db2/runtime.html.
In contrast, the DB2 Client includes sum the functions establish in the DB2 Runtime Client plus functions for client-server configuration, tools for database administration and application development, samples, and more. For example, this client includes the Configuration aide that provides graphically administration and connectivity tools, as well as a host of programming samples, and so on. The DB2 9 Client replaces the functions establish in both the DB2 8 Application progress and DB2 8 Administration clients.
A DB2 Client's footprint is directly correlated to the components you select to install and can elect between 200 MB and 800 MB depending on the options you select. The process to install a DB2 Client is very similar to a DB2 data server. You can download a DB2 Client at http://www-304.ibm.com/jct03002c/software/data/db2/runtime.html.
The selection of which DB2 client to install should exist based on the requirements of the application on the client machine. For example, if you Enjoy a database application developed for Linux, UNIX, or Windows and you accomplish not require the DB2 administration or application progress tools from a Windows workstation, yet want to support applications written in multiple programming languages like .NET and Java, you should install the DB2 Runtime Client on that workstation.
Some enterprises prefer to deploy the DB2 Runtime Client code remotely on a dedicated server. In these environments, remote workstations necessity to access the DB2 Runtime Client code remotely from a code server before accessing to DB2. This character of configuration is known as a thin client. A thin-client configuration can provide many benefits, such as a central catalog directory of sum database connections and a unique footprint of code to manage. The trade-off is that clients must load the client .dlls from the code server before accessing the remote data server. It should exist notable however that this performance hit is only "noticed" on the initial connection. Once the client code is loaded on the client workstation, subsequent calls to the code server are not needed.
When you want to deploy your DB2 application, you only necessity to ensure that a DB2 Runtime Client is installed on each workstation executing the application. figure 1-10 shows the relationship between an application, a DB2 Runtime Client, and the DB2 data server. If the application and database are installed on the same server, connectivity is considered to Come from a local client. If the application is installed on a system other than the DB2 data server, its connectivity is considered to Come from a remote client.
Figure 1-10 Accessing a DB2 data server using the DB2 Runtime Client
DB2 client connectivity can exist configured using various supported communication protocols. The supported protocols vary according to operating system:
Some larger enterprises and independent software vendors (ISVs) want to deploy their applications written in unique language without the overheard of installing and maintaining a DB2 client on each client workstation. Despite the much smaller footprint of the DB2 Runtime Client in DB2 9, IBM makes available two drivers that can exist deployed for connectivity on their own, outside of a DB2 Runtime Client or DB2 Client installation.
The IBM Driver for JDBC and SQLJ can exist deployed to support Java-based connectivity to a DB2 data server. This driver is about 2 MB in size and can easily exist embedded within your application. In fact, it comes with a royalty-free distribution license for this very purpose.
You should note however that although this driver can connect to the entire DB2 family, if you're connecting to a DB2 for i5/OS, DB2 for VM/VSE, or DB2 for z/OS data server, you necessity to additionally license this connectivity with DB2 Connect (covered in the next section) to ensure you are compliant with respect to licensing.
It's essential to note that the IBM Driver for JDBC and SQLJ solely supports Java applications. Aside from not including tooling and documentation, this driver doesn't support data server connectivity using other APIs. For example, you can't support a .NET application using this driver. You can download this driver at www14.software.ibm.com/webapp/download/preconfig.jsp?id=2004-09-20+10%3A09%3A21.003415R&cat=database&fam=&s=c&S_TACT=105AGX11&S_CMP=DB2.
DB2 9 includes a recent standalone driver for CLI and ODBC applications called the IBM DB2 Driver for ODBC and CLI. This driver delivers the same benefits and restrictions as the IBM Driver for JDBC and SQLJ to your DB2 environment, except it solely supports CLI/ODBC connections. You can download this driver at www14.software.ibm.com/webapp/download/preconfig.jsp?id=2004-09-20+13%3A44%3A48.813589R&cat=database&fam=&s=c&S_TACT=105AGX11&S_CMP=SPLT.
The main benefits of the IBM DB2 Driver for ODBC and CLI are:
DB2 Connect is a sunder product family that licenses client connectivity from distributed platforms to the DB2 family running on i5/OS, VM/VSE, and z/OS operating systems (hereafter referred to as mainframe). Although communications between any members of the DB2 family consume the Distributed Relational Database Architecture (DRDA), you Enjoy to explicitly license access from DB2 for Linux, UNIX, and Windows clients to these data servers.
A client accessing DB2 running on the mainframe is generally referred to as a DRDA Application Requester (DRDA AR) and the DB2 server that manages the client connection as a DRDA Application Server (DRDA AS). DB2 Connect only uses TCP/IP as the transport protocol between a DRDA AR and DRDA AS.
Some of the major capabilities provided by DB2 Connect include:
DB2 Connect is often used to enable mainframe resources for Web access, better integrate legacy and inheritance systems with recent deployments on distributed platforms, modernize the application progress smack for mainframe progress (for example, affecting from COBOL to Java), and off-loading progress cycles to lower-cost operational environments.
Depending on the DB2 Connect edition you purchase, you can create a connectivity architecture for single- or multi-tier environments.
You can survey in figure 1-11 that there are many ways to implement a DB2 Connect product. In a multi-tier environment, you consume DB2 client software to connect to the DB2 Connect gateway (in a client/server model) passing the connection context to to the mainframe resource. In a Web-based deployment, you may Enjoy DB2 Connect on its own or collocated with the application server. Depending on your configuration, you may or may not necessity to install a DB2 client.
Figure 1-11 Using DB2 Connect is a single-tier or multi-tier environment
DB2 Connect products can exist added on to an existing DB2 data server installation, or act as a standalone gateway. Either way, it's purchased separately from DB2. If you are using one of drivers discussed earlier in this chapter, technically you can acquire the connection to a mainframe DB2 resource, but you soundless necessity to purchase a cogent DB2 Connect license. There are a number of DB2 Connect editions available and each is suited for a particular implementation of the DB2 Connect software. With the exception of DB2 Connect PE, sum of the DB2 Connect editions proffer the same duty and features; they are merely differentiated by capability. sum editions of DB2 Connect PE are considered gateways since they provide client/server access to workstations. To connect to a DB2 Connect gateway, you simply consume a DB2 client.
DB2 Connect Personal Edition (DB2 Connect PE) is similar to DB2 Personal Edition in that it is used for unique workstations and doesn't provide its users with any server capabilities. Using DB2 Connect PE, you can acquire direct connections to DB2 running on the mainframe. In figure 1-11, the desktop users likely Enjoy DB2 Connect PE installed in their workstations. DB2 Connect PE can also act as a regular DB2 client and connect to distributed versions of the data server as well. Some environments deploy DB2 Connect with both direct and gateway connectivity. For example, a developer may acquire direct connections using the DB2 Connect PE software for unavoidable stages of the progress cycle. But once the application is in production, they may consume the DB2 Connect PE software to connect to a DB2 Connect gateway to elect edge of the features it provides, such as load balancing, connection optimization, high-availability, and more. DB2 Connect PE is licensed on a per-workstation basis.
DB2 Connect Enterprise Edition (DB2 Connect EE) can exist licensed using two different user-based options: the number of Authorized Users or the number of Concurrent Users. DB2 Connect EE provides the competence to implement a three-tier connectivity architecture that allows you to seclude connectivity to mainframe resources to a specific tier in your architecture. Again, DB2 clients (or drivers) are used to connect to the gateways, and then the DB2 Connect software manages the connection context to the mainframe.
DB2 Connect Application Server Edition (DB2 Connect ASE) is licensed by the total VU rating of sum the applications servers that connect to the mainframe. The VUs that you purchase Enjoy nothing to accomplish with how many DB2 Connect servers you set up, or what their rating is. For example, if your Web server farm was rated at 1,000 VUs and you set up a DB2 Connect gateway farm rated at 5,000 VUs, you would Enjoy to buy 1,000 VUs of DB2 Connect ASE. DB2 Connect ASE is well suited for environments where you anticipate to survey more growth of mainframe resource than your Web tier because its costs are directly linked to the VU rating of the Web serving tier.
DB2 Connect Unlimited Edition (DB2 Connect UE) is available for i5/OS and z/OS. DB2 Connect UE for i5/OS is licensed by the number of managed processors attached to the i5/OS partition while DB2 Connect UE for z/OS is licensed with a foundation server license plus a per-unit permeate for the MSU rating of the System z server you are connecting to. DB2 Connect UE is well suited for environments that Enjoy flat mainframe cycle growth and cumbersome Web tier growth as the costs of DB2 Connect UE are directly correlated with the capacity of the mainframe resource. DB2 Connect UE comes with a free copy of Mobility on require to flux mainframe data to occasionally connected devices, as well as DB2 Connect PE. Essentially, this edition of DB2 Connect, as its denomination would imply, allows for unlimited deployments.
There's so much more to the DB2 Connect product than what's detailed in this section. In fact, the denomination DB2 Connect is delusive because connectivity is just a wee share of what this product can do; however, these details are outside the scope of this book.DB2 Replication
DB2 Replication allows for data to exist propagated from one location to another. SQL-based replication, also know as Data Propagator (DPROPR) replication, is a free component of the DB2 for Linux, UNIX, and Windows data servers (it's a paid feature on the mainframe). You can also extend this replication capability to support a wide variety of data servers, including DB2, Oracle, Microsoft, Sybase, Informix, IMS, Lotus Notes, and flat files with WebSphere Replication Server.
An example of SQL-based replication is shown in figure 1-12. SQL-based replication has been around for over a decade and has proven itself to exist extremely flexible, resilient, smooth to set up, and scalable.
Figure 1-12 SQL-based replication extended with WebSphere Replication Server
In figure 1-12 you can survey the broad achieve of the SQL-based replication technology when it is extended with the WebSphere Replication Server product. As you may recall, distributed versions of DB2 Come with the DPROPR technology built in and can support replication subscriptions across the DB2 family. The core capabilities of a distributed data server with respect to replication are shown in the top-left and top-right portions of figure 1-12.
When you buy WebSphere Replication Server, you also procure Q-based replication (Figure 1-13). In Q-based replication, each message represents a transaction that is placed on a WebSphere MQ succession message queue. This replication is known for its highly parallel apply process and loaded contest detection and resolution services.WebSphere Federation Server and WebSphere Information Server
WebSphere Information Server provides features and functions to place, publish, integrate, find, cleanse, and access data. The federation capabilities are worth mentioning as they relate to data access. WebSphere Federation Server contains a subset of the functionality establish in WebSphere Information Server, namely the federation capabilities (and hence will exist the focus of this section). You can learn more about WebSphere Federation Server and WebSphere Information Server at www.ibm.com/software/data/integration/.
A federated system is a distributed database environment that appears as a unique virtual database to terminate users and applications. The WebSphere Federation Server technology (some of which is built into DB2) allows SQL statements to transparently access, join, or update data located across heterogeneous data sources. Federated support enables the DB2 data server to evaluate global statistics on sum data sources in order to optimize requests for the remote data. For example, the global optimizer can consume erudition of source statistics, source indexes, source functions, server and network speeds, and so on.
The SQL support in a DB2 federated environment supports the same SQL as a non-federated environment, including advanced object-relational SQL operations across the federated data sources, such as recursive SQL, common table expressions (CTEs), and more. If the remote data source doesn't Enjoy this capability, DB2 will compensate for the missing functions.
Perhaps the greatest benefit to a federated system is that developers only Enjoy to learn a unique lingo of SQL; namely, the DB2 ANSI-compliant SQL API. If an external data source has different data types or non-standard SQL, DB2 will transparently compensate for missing functions and transform data types. For example, SQL Server 2005 has a MONEY data character whereas DB2 uses a DECIMAL data character to support currency. Without the WebSphere Federation Server technology, a developer would Enjoy to know the differences between these data servers, or cast them to like data types using OLE DB. With WebSphere Federation Server, developers just code as if they were always accessing DB2 data, and the ease is taken supervision of.
An example of federated access is shown in figure 1-14.
Figure 1-14 The power of federation—any data, one API
In figure 1-15 you can survey the technology components that acquire up a federated database. Nicknames are used to implement a low contour of granularity with respect to the data sources you want to acquire available. Nicknames essentially are local aliases on remote tables, although they can exist mapped to specific rows and columns. A collection of nicknames is located within a server that represents that actual data source. For example, in figure 1-15 Oracle is one such data source, so the server component would limn a specific Oracle database. sum the SQL eventually flows through a wrapper, which is a library of code that allows access to a particular class of data servers. Connections made to these servers consume their indigenous protocol; for example, the Oracle connection will consume the Net8 client.
You can survey in figure 1-14 that with WebSphere Federation Server you can pretty much extend the achieve of DB2 to any data source in your environment. For example, in the life sciences industry, scientists necessity access to specialized data to support their research related to drug discovery. IBM offers a set of Life Sciences wrappers that can exist used to build a federated system that can access data useful to scientists, including excel spreadsheets, image data, flat files, and blight (Basic Local Alignment Search Tool).
If a wrapper is not available for purchase, there is a software developer's kit (SDK) that you can consume to build your own.Database Enterprise Developer's Edition
IBM offers a special discounted suite of Information Management products that you can purchase at a discount for development, evaluation, demonstration, and testing of your application programs; this edition is called Data Enterprise Developer Edition (DEDE).
Some of the products included in this comprehensive developer offering are:
Most of the products within DEDE are available for sum the platforms that DB2 Enterprise supports (unless of course a product doesn't exist on a specific platform). The data server where you install DEDE can exist on a platform that is different from the one on which the application will eventually exist deployed or tested because of the common code foundation used in the distributed DB2 environment. In fact, almost any applications developed using DEDE can exist executed on any system that has DB2 client software (or specific drivers for which the application is written) installed.
The application progress environment provided with DEDE allows application developers to write programs using today's most celebrated methodologies, including:
DEDE also includes the necessary programming libraries, header files, code samples, and pre-compilers for sum of the supported programming languages.DB2 Developer Workbench
The DB2 9 Developer Workbench (DB2 DWB) replaces the DB2 8 progress Center. The DB2 DWB is an Eclipse-based graphical environment that supports the rapid progress of DB2 SQL and Java stored procedures, SQL scalar and table user defined functions (UDFs), SQL statements, XQuery statements, and Web Services. However, there's so much more to this list. For example, the DB2 DWB includes an SQL editor that's enriched with syntax colorization and code assistants, as well as teaming support, compare utilities, and more.
The DB2 DWB is a sunder utensil and is maintained sunder from a DB2 data server. You can download it from www-304.ibm.com/jct03001c/software/data/db2/ad/dwb.html.
The DB2 DWB is really meant for power DBAs that aren't coding experts but require rapid progress assistance for building commerce logic for their data servers. Depending on your environment, you may elect to consume another utensil like Toad for DB2 or Visual Studio. unadulterated developers will likely elect to consume the plug-ins provided with DB2 9 into their respective IDEs, although they are free to consume the DB2 DWB. For the most part, you can accomplish the same tasks in any of the tools that IBM ships or the integration points in specific IDEs.
A snapshot of the Developer Workbench screen is shown in figure 1-16.DB2 Extenders
DB2 Extenders proffer the competence to exploit data outside of conventional rows and columns to involve the manipulation of special data types (for example, spatial types that Enjoy associated LAT/LONG coordinates and SQL-based functions to operate on them), searching services, and more. The purpose of the DB2 Extenders is to provide for the management of this data through the close DB2 SQL API.
The DB2 Extenders encapsulate the attributes, structure, and behavior of these unstructured data types and stores this information in DB2. From the developer's perspective, the DB2 Extenders materialize as seamless extensions to the database and enable the progress of multimedia-based applications. In other words, a spatial data character is no different than a built-in data character that they may exist accustomed to. This section briefly details the DB2 Extenders that are provided by IBM.DB2 Spatial Extender
The DB2 Spatial Extender (DB2 SE) provides the competence to create spatially conscious data objects and store them within your DB2 database, along with other spatially related objects like (LAT/LONG) coordinates and more. Almost sum industries could benefit from this free technology in DB2. For example, the banking and finance industry could visually envelope customer segments for brand location identification. Municipal governments could consume this technology for flood modest identification, the retail industry for billboard locations, and more. This seems clear-cut when you esteem that almost sum data has some sort of spatial component to it: they sum Enjoy an address, merchandise in a warehouse has a stock location, and so on.
The commerce benefit of the DB2 SE lies in the notion that it's a lot easier to spot visually represented information than data reported in rows and columns.
When you enable your DB2 database for the DB2 SE, you can interact with your data using SQL or specialized spatial tools from other vendors. The point is that with the DB2 SE, DB2 understands the spatial "dialect" and the operations that you want to accomplish with it.
For example, a telematics application on a PDA may provide its users with a list of nearby Chinese restaurants that serve Peking Duck based on the dynamic request of this user. In this case, after the client's PDA creates a location box using Global Positioning System (GPS) coordinates, it could generate SQL statements similar to the following:SELECT NAME, DESCRIPTION, ADDRESS FROM RESTAURANTS WHERE OVERLAPS (LOCATION, BOX(GETGPS(),2000,2000)) AND CATEGORY = 'CHINESE' AND DOC CONTAINS(MENU,'PEKING DUCK');
OVERLAPS is a spatial duty that shows interested data in a binding box defined by the OVERLAPS restrict specification; there are many other spatial functions, including INTERSECTS, WITHIN, BUFFERS, and so on.DB2 Geodetic Extender
The DB2 Geodetic Extender builds upon capabilities available in the DB2 Spatial Extender and adds compensation for real-world objects like the curvature of the earth's surface. The algorithms in this extender seek to remove the inaccuracies introduced by projections and so on. This extender is available only for DB2 Enterprise as share of the Data Geodetic Management feature.DB2 Net Search Extender
The DB2 Net Search Extender (DB2 NSE) combines in-memory database technology with text search semantics for high-speed text search in DB2 databases. Searching with it can exist particularly advantageous in Internet applications where performance is an essential factor. The DB2 NSE can add the power of rapid full-text retrieval to your DB2 applications. Its features let you store unstructured text documents of up to 2 GB in databases. It offers application developers a fast, versatile, and quick-witted pass of searching through such documents.
Additionally, the DB2 NSE provides a loaded set of XML searching capabilities with advanced search features like sounds-like, stemming, and so on. It is shipped free in DB2 9 (it was a chargeable extender in DB2 8) to facilitate non-XML index searching of XML data stored in pureXML columns.DB2 XML Extender
The DB2 XML Extender is provided with DB2 and allows you to store XML documents in DB2; it also gives you the competence to shred and store XML in its component parts as columns in multiple tables. In either case, indexes can exist defined over the elements or attributes of an XML document for rapid retrieval. Furthermore, text and fragment search can exist enabled on the XML column or its decomposed parts via the DB2 Net Search Extender. The DB2 XML Extender can also wait on you formulate an XML document from existing DB2 tables for data interchange in business-to-business environments.
You may recall that the pureXML add-on feature pack is available for sum DB2 9 data servers. Indeed, this can antecedent confusion since the DB2 XML Extender is shipped for free in DB2 9. You should esteem the DB2 XML Extender as stabilized technology. In other words, it is no longer being enhanced and shouldn't exist considered for most XML applications. The DB2 XML Extender's approach to storing XML is to shred the XML to relational tables or stuff it into a big object. When you consume this technology to persist XML data, you Enjoy to acquire earnest trade-offs with respect to performance, flexibility, and so on. In addition, you Enjoy to consume specialized functions to implement Spathe searches, and data types are abstracted from foundation DB2 data types. Quite simply, the pass you interact with the DB2 XML Extender isn't natural for XML programmers and DBAs alike.
In contrast, the pureXML feature in DB2 9 provides services such that no compromises between flexibility (what XML was designed for) and performance (one of the reasons why you want the data server to store your XML) necessity to exist made when storing your XML data. For example, to generate XML documents from relational tables, you simple consume the SQL/XML API instead of the cumbersome DB2 XML Extender functions. You can validate XML documents against Sods instead of only document character definitions (Ds) as is the case with the DB2 XML Extender, and more. They strongly recommend this feature for most of your XML-based applications.
The following is a book excerpt from DB2 9 for Linux, UNIX, and Windows: DBA Guide, Reference, and Exam Prep, 6th Edition, by George Baklarz and Paul Zikopoulos. It is reprinted here with permission from International commerce Machines Corporation; Copyright 2008. Read the chapter excerpt below to learn about the basics of DB2 tools and products or download a free .pdf of this chapter: "DB2 tools and products for Linux, UNIX and Windows: The basics."
In this chapter you will exist introduced to the DB2 family of products that flee on the Linux, UNIX, and Windows operating systems. This version of DB2 is often referred to as the distributed version to differentiate it from the DB2 for z/OS® version that runs on an IBM mainframe.
DB2 has the competence to store sum kinds of electronic information. This includes traditional relational data, data encoded within XML as well as structured and unstructured binary information, documents and text in many languages, graphics, images, multimedia (audio and video), information specific to operations like engineering drawings, maps, insurance claims forms, numerical control streams, or any character of electronic information. This chapter illustrates some of the ways to access data in a DB2 database using some of the interfaces provided within the DB2 family. A description of each of the DB2 products are provided to illustrate some of DB2's features and functions.
Information as a Service
The DB2 Data Server is an essential share of IBM's Information as a Service software portfolio that serves as the atomic plane for the broader IBM On require architecture.
Figure 1-1 IBM Service Framework for an On require business
In figure 1–1 you can survey that the IBM software portfolio has really evolved into a collection of lofty value services provided by various IBM software portfolio offerings. The backbone fabric of this IBM reference architecture is the Enterprise Service Bus (ESB) that is used to facilitate communications across this loaded set of services.
IT Service Management is mostly provided by various Tivoli® products. The Tivoli portfolio is built around four key disciplines or pillars:
Services from these pillars can exist used to collectively manage your entire IT framework. For example, Tivoli Storage Resource Manager services can exist used enterprise-wide to monitor and report on heterogeneous storage resources to multiply storage utilization, identify and resolve potential problems, and ensure application availability through policy-based automation.
Development Services are the culmination of various Rational-based products that are built on the open source Eclipse platform. For example, Rational® ClearCase® provides source control services, and Rational Application progress empowers application developers with a loaded set of services that can exist used to develop applications, Web pages, and extended custom services for implementation in a Services Oriented Architecture (SOA) or loosely coupled application framework.
Services that enable interaction are typically share of the Lotus® suite of products that enhance collaboration and idea sharing across the enterprise and beyond. Products like Lotus Sametime® Connect can exist used for messaging and more.
A number of services in the framework illustrated in figure 1-1 are provided by the WebSphere® portfolio. For example, a product like WebSphere Integration Developer helps you define commerce process flows in the measure commerce Process Execution Language (BPEL), which are used to implement process services that in whirl wait on you define, orchestrate, and automate commerce policies. The Enterprise Service Bus (ESB) is provided by the WebSphere ESB product that provides your enterprise services with transformation, transport switching, and routing remediation among other services. Perhaps the most distinguished product of the WebSphere brand is the WebSphere Application Server that provides a runtime framework for J2EE®-based operations that are share of the Infrastructure Services component.
Finally there's the Information Services which limn the superset of the capabilities you'll learn about in this book. The specific set of services that are typically establish in this share of the IBM reference architecture are shown in figure 1-2.
Figure 1-2 IBM Information Services defined
The services shown to the perquisite in figure 1-2 are hierarchical in nature. In other words, as you travail from bottom to top, the services provided become richer and more commerce oriented.
For example, Master Data Management services are provided by the WebSphere Product seat and WebSphere Customer seat products. Master data are facts that narrate your core commerce entities: customers, suppliers, partners, products, bill of materials, employees, and so on. The discipline of Master Data Management seeks to decouple master information from individual applications spread across the enterprise and create a central, application independent, resource. The terminate result is a simplification of ongoing integration tasks and recent application development. This discipline addresses key issues such as data character and consistency proactively rather than "after the fact"; for example, in a data warehouse (a lower service in this taxonomy). There is also a set of entity resolution services that apt within the Master Data Management service tier.
Business Intelligence services are provided by the DB2 Data Warehouse editions that you'll learn more about later in this chapter. Content Manager services are provided by the set of Content Management products and are used for document management, archiving, regulatory retention, and are a basis by which unstructured information (such as FAXes, video, voicemail, and so on) can exist searched and folded into the information asset.
Information Integration services seek to provide enterprises with ways to share, place, publish, cleanse, and enrich data establish in the lower-level data management services. WebSphere Federation Server and its parent WebSphere Information Server are two such products that wait on implement these services.
Finally, the Data Management services tier is the foundation upon which the other services are built. IBM has a number of data servers that apt into this tier, including DB2, Informix®, IBM Cloudscape™, U2, and IMS™.
This book is specifically about DB2 in this service tier. Specifically, you'll learn how DB2 can provide any number of the high-value data-centric services shown in figure 1-3.
Figure 1-3 The data services provided by DB2, the focus of this book
For more information on the entire IBM software portfolio and how they are mapped to the illustrated services shown Figures 1-1 and 1-2, mention to the IBM Web site at www.ibm.com for more details.
The DB2 family of data servers executes on Windows, Linux (which can exist flee on the entire spectrum of IBM's hardware: System i™, System z™, System x™, and System p™), Solaris™ (both SPARC®-based and Intel®/AMD™-based installations), HP-UX™ (both PA-RISC™-based and Itanium-based installations), i5/OS®, VSE/VM, z/OS, and on pervasive platforms (like Windows Mobile Edition, Blue- Cat® Linux, Symbian®, Palm OS®, J2ME® platforms like the RIM® lackberry®, and more).
The DB2 code foundation is optimized for each platform to ensure maximum performance and integration. DB2 for Linux, UNIX, and Windows shares about a 98 percent common code foundation with platform-specific optimizations at the operating system interface (OSI) plane (Figure 1-4).
This means that once you've learned how to administer a DB2 for AIX system, for the most share you'll know how to manage DB2 for Linux or DB2 for Windows; this is the judgement why there is a unique DB2 certification for sum the distributed platforms.
Figure 1-4 The DB2 code for Linux, UNIX, and Windows is virtually the same
DB2 for i5/OS and DB2 for z/OS are optimized for their respective environments. For example, DB2 for z/OS is based on a shared-everything disk architecture where the hardware-assisted Coupling Facility is used to serialize access to the shared disk. No such hardware exists for Linux, UNIX, and Windows, and therefore DB2 on these platforms uses a shared-nothing architecture. For this reason, administration tends to vary between these platforms (though many concepts and features are similar). However, the SQL API is 98% common to sum the platforms where DB2 runs, allowing applications written on one platform to exist easily ported to another. This means that you can build an application on DB2 for Windows and port it effortlessly to DB2 for z/OS. If you build your application according to the SQL Reference for Cross-Platform progress handbook, your application will exist 100% portable across the DB2 family.
There are other synergies among DB2 running on Linux, UNIX, and Windows, as well as the other DB2 family members. For example, the JDBC driver used for DB2 for z/OS is exactly the same code as is used for DB2 for Linux, UNIX, and Windows. So while there may exist variations in specific data definition language (DDL)-based tasks, the data manipulation language (DML) and client APIs are similar.
The DB2 for Linux, UNIX, and Windows Data Server
In the distributed environment, DB2 is available in a number of different packaging options, called editions. Furthermore, DB2 is also available as share of other packages that accommodate additional features and tooling rather than just the foundation data services provided by DB2.
The mainstream DB2 editions are shown in figure 1-5:
Figure 1-5 The distributed DB2 family
For the most part, each edition builds on its child in this hierarchy. For example, if a feature or functionality is available in DB2 Workgroup Edition, it's likely that it's also a share of a higher-level edition, like DB2 Enterprise Edition.
DB2 Everyplace Edition
DB2 Everyplace (DB2e) is a tiny "fingerprint" database that's about 350K in size. It is designed for low-cost, low-power, wee form-factor devices such as personal digital assistants (PDAs), handheld personal computers (HPCs), and embedded devices. DB2e runs on a wide variety of handheld devices, with support for Palm OS 5.x, Windows Mobile 2003 for Pocket PC, Windows Mobile 2005 for Pocket PC, Windows CE.NET, traditional Windows desktop platforms, Symbian OS Version 7/7s, QNX® Neutrino® 6.2, Linux distributions running with the 2.4 or 2.6 kernel, embedded Linux distributions (like BlueCat) running with the 2.4 or 2.6 kernel, and more.
The SQL API used to develop DB2e applications is a subset of that used for building full-fledged DB2 data server applications. This means that enterprise applications, for the most part, can exist easily extended to involve mobile devices. More importantly, it means that if you Enjoy DB2 skills, you Enjoy DB2e skills. In addition, DB2e is extremely supple for developers, with support for Open Database Connectivity (ODBC), Java Database Connectivity (JDBC), .NET (including the ADO.NET 2.0 API), and the DB2 summon plane Interface (CLI) APIs.
DB2e is a very simple-to-use data server that requires virtually no maintenance. Typical database administrator (DBA) operations like reorganizations and statistics collection are sum performed automatically. Another nice thing about developing DB2e applications is that the database engine is platform independent, so it provides flexibility: You can seamlessly flux DB2e databases between devices. For example, you could flux a DB2e database populated on a Pocket PC device to a Symbian smartphone, or whatever other supported device you have, without the necessity to accomplish anything. This feature, coupled with the loaded support for application development, enables developers to quickly build, deploy, and support mobile applications on sum platforms.
DB2e is available in two editions: DB2 Everyplace Database Edition (DB2e DE) and DB2 Everyplace Enterprise Edition (DB2e EE). The database component of DB2e DE is the same as DB2e EE; however, DB2e DE has no synchronization middleware to extend or synchronize data to back-end enterprise data servers (although it does Come with command line-based import and export utilities). DB2e DE is primarily used for applications that require an embedded database or a local relational storage facility that is exposed to endusers through some sort of application (they never really survey the database) yet Enjoy stringent footprint requirements because of the device.
DB2e EE distinguishes itself from DB2e DE in that it comes with a data synchronization component called the DB2e Synchronization Server (DB2e Sync Server). The DB2e Sync Server allows you to manage subscriptions and security controls for data that is distributed wirelessly to your hand-held devices and manage data changes on the client devices back into the data center. The DB2e Sync Server also comes with facilities for contest resolution, application deployment, device identification controls, management policies, and more.
The DB2e Sync Server can synchronize DB2e and Apache Derby/IBM Cloudscape data servers with back-end JDBC-enabled compliant data servers (for example, DB2, Oracle, Informix, SQL Server™, and so on). In addition, there is a special DB2 family synchronization adapter that uses the Data Propagator™ (DPROPR) SQL-based replication technology (which is included in the distributed version of DB2).
The number of concurrent synchronizations that the DB2e Sync Server can support is relative on the hardware configuration of that server, the associated workload, and data change rates. If you necessity to scale to exploit very big concurrent synchronizations, you can install any Java application server (like IBM WebSphere Application Server). DB2e also supports enhanced scalability and high-availability through its support for DB2e Sync Server farm configurations that allow you to cluster a number of DB2e Sync Servers to provide load balancing and high-availability services.
Figure 1-6 A DB2e Enterprise Edition environment
In figure 1-6 you can survey the flux of data in a DB2e EE environment. For example, data is pulled from a database in Tier 3 (the far perquisite of the figure) and placed on a mobile device in Tier 1 (the far left). Tier 1 is typically composed of occasionally connected clients that operate on data and then consume the services provided by Tier 2 (the middle of the figure where the DB2e Sync Server resides) to shove those changes back to Tier 3. Tier 2 handles issues like contest remediation and subscription management to ensure that the data character is maintained throughout its lifecycle until it's at rest.
Apache Derby/IBM Cloudscape
In 2005, IBM donated $85 million worth of relational database management system (RDBMS) code to the open source community, and the Apache Derby database was born. Apache Derby and IBM Cloudscape are the same databases; the dissimilarity is that IBM Cloudscape is sold by IBM with IBM's award-winning 24*7 support and has some add-on features as well.
If you hadn't heard of IBM Cloudscape before the donation news, you'll probably exist surprised to learn how many partners, customers, and software packages consume this data server. In fact, more than 80 different IBM products consume the IBM Cloudscape data server for its portability, smooth deployment, open standards-based Java engine, wee footprint, and more. IBM Cloudscape is a component that is transparent to products such as WebSphere Application Server, DB2 Content Manager, Web- Sphere Portal Server, IBM Director, Lotus Workplace, and many others.
IBM Cloudscape is a Java-based RDBMS that has a 2MB footprint. It's compatible with DB2, supports advanced functions (such as triggers and stored procedures), is smooth to deploy, and requires no DBA effort. These same characteristics hold cogent for the open source Apache Derby as well.
We chose to involve the Apache Derby/IBM Cloudscape data servers in this discussion because their SQL API is 100% compatible with the DB2 data server editions in figure 1–5. This means that you can elect any Apache Derby/IBM Cloudscape database and application and flux it to a full-fledged DB2 data server if you necessity more scalability, or you necessity to elect edge of features that aren't establish in these data servers. In fact, a component of DB2 9, called the DB2 Developer Workbench, provides a built-in facility to migrate Apache Derby/IBM Cloudscape schemas and data to a DB2 data server.
DB2 Personal Edition
DB2 Personal Edition (DB2 PE) is a full-function database that enables unique users to create databases on their workstations. Since it's limited to unique users (it doesn't support inbound client request for code), it's generally not referred to as a data server (although the DB2 engine behind DB2 PE is that same DB2 engine for sum editions in figure 1-5). This product is only available on Linux and Windows. DB2 PE can also exist used as a remote client to a DB2 data server. Applications written to execute on DB2 PE are fully portable to the higher-level editions of the DB2 family in figure 1-5.
DB2 PE is often used by terminate users requiring access to local and remote DB2 databases, or developers prototyping applications that will exist accessing other DB2 databases. In addition, since it includes the pureXML™ technology free of charge, DB2 PE is also a advantageous selection for those looking to acquire DB2 9 pureXML skills. In many cases, because it includes replication features, DB2 PE is used for occasionally connected applications (like field research, sales force automation, and so on) where a richer feature set is required than what's offered by DB2e or Apache Derby/IBM Cloudscape.
More information about IBM DB2
It was over the final holiday season that I wanted to elect some time and play around a bit with data. The outcome was rather different than I initially expected. Rather than having worked with the data, I spent a lot of time trying to procure some CSV data loaded into a database. I knew that there are considerable tools such as SQL Developer out there that acquire loading CSV data trivial, but I wanted something that I could execute via the command line, not requiring a GUI. The simple judgement was that I wanted to script the loading share rather than having to execute some manual, potentially error-prone steps whenever loading some data again. Too late I establish out, actually just final week, that SQLcl already had what I was after, a load command that does exactly what I wanted:SQL> wait on load LOAD ----- Loads a comma separated value (csv) file into a table. The first row of the file must exist a header row. The columns in the header row must match the columns defined on the table. The columns must exist delimited by a comma and may optionally exist enclosed in double quotes. Lines can exist terminated with measure line terminators for windows, unix or mac. File must exist encoded UTF8. The load is processed with 50 rows per batch. If AUTOCOMMIT is set in SQLCL, a commit is done every 10 batches. The load is terminated if more than 50 errors are found. LOAD [schema.]table_name[@db_link] file_name
Unfortunately, back then, Google didn't proffer me this insight when looking for "load csv data into oracle," so I was stuck with the methods I already knew and that I establish as too cumbersome to deal with. After all, sum I wanted was a simple utensil that loaded data from CSV files into a table and matches the column names with the header of the file:cat people.csv "first_name","last_name","city" "Gerald","Venzl","San Francisco" "Andreas","Pumberger","New York City" SELECT * FROM PEOPLE FIRST_NAME LAST_NAME CITY ---------- --------- ------------- Gerald Venzl San Francisco Andreas Pumberger recent York City
I knew that what I was after wasn't difficult at sum and was probably just a few lines of code, so after hours and hours of trying to load that data, I wrote a diminutive Python program to accomplish exactly what I needed. Writing the program took me just about two hours and around 300 lines of code. After that, I was able to load the data in an smooth and scriptable pass into my database. Thinking of how much time I Enjoy spent looking for this and trying different means to no desired outcome, I thought that I might as well just wait on the world and provide this script to others as well. Of course, it's not difficult to write such a diminutive program, but after all, if I can reclaim somebody out there some time, why not? So I polished the code I Enjoy written, wrote some documentation around it, and named the program csv2db. It is now available under https://github.com/csv2db/csv2db and can load data into an Oracle, MySQL, PostgreSQL, and Db2 database.
In the meantime, I Enjoy added some nice diminutive features to it, such as:
The final feature is nice since most CSV files Come in compressed contour and uncompressing them first adds no benefit but just fills up the disk unnecessarily.
The CREATE TABLE feature came out of an immediate necessity by myself. I had many CSV files (50+) and not sum of them had the same structure (because their structure changed over time). I really didn't want to uncompress them one by one, copy/paste sum the headers into a text file, and then figure out what columns I needed in my table. I just wanted to procure the data into the database and then cleanse and process it further with SQL. So what I was after was something that just gave me a create table statement with sum the columns from the CSV files, their data character being just string, no constraints or anything else. In other words, just allow me to load the data into a staging table and elect it from there. While this isn't required anymore once the CSV column structure is known, it makes getting started with new, unknown CSV data just so easy.
Loading data from a CSV file into a database with csv2db is a simple one-line command:$ ./csv2db load --file 201811-citibike-tripdata.csv.gz \ --table citibikes --dbtype oracle --host dbserver1 \ --user csv_data --password csv_data --dbname ORCLPDB1 Loading file 201811-citibike-tripdata.csv.gz Done
This command will load sum data from the file 201811-citibike-tripdata.csv.gz into the table CITIBIKES. The ease of the commands are database connections details. --dbtype tells csv2db which database driver to use, --host, --dbname, --user, and --password are the connection details to the database and the database user. By default, the default port for each database will exist used, but this can exist overwritten with the --port parameter, if required. The data character conversion is left to the implicit data character conversion of the database. That means that sum inputs are sent as strings and it's up to the database to transform them into the respective data types of the individual columns.
If you procure a recent set of CSV files and want to create a staging table for them, you can accomplish so again with a simple one-line command:$ ./csv2db generate -f *-citibike-tripdata.csv.gz \ --table STAGING --column-type VARCHAR2(1000) CREATE TABLE STAGING ( END_STATION_LATITUDE VARCHAR2(1000), GENDER VARCHAR2(1000), START_STATION_LATITUDE VARCHAR2(1000), END_STATION_NAME VARCHAR2(1000), BIRTH_YEAR VARCHAR2(1000), START_STATION_NAME VARCHAR2(1000), STOPTIME VARCHAR2(1000), END_STATION_ID VARCHAR2(1000), STARTTIME VARCHAR2(1000), START_STATION_LONGITUDE VARCHAR2(1000), START_STATION_ID VARCHAR2(1000), BIKEID VARCHAR2(1000), USERTYPE VARCHAR2(1000), TRIPDURATION VARCHAR2(1000), END_STATION_LONGITUDE VARCHAR2(1000) );
This command scans sum files matching the pattern *-citibike-tripdata.csv.gz, extracts their headers, i.e. the first line of each file, and produces a CREATE TABLE statement with sum the columns in the CSV headers. Spaces in the header columns are automatically replaced by _. The --table parameter allows you to specify a table name, and when omitted, you will procure a CREATE TABLE <TABLE NAME> instead, and you can fill in the table denomination afterwards. The --column-type parameter allows you to specify the desired data character for sum columns. Note, the goal for csv2db here is not to parse the entire CSV file and guess the data types for each column. Instead, it just gives you the syntax to create a staging table that will hold your data. It is up to you to figure out the data types you want to consume or whether you want to load data into such a staging table and then accomplish an INSERT AS SELECT * afterwards, etc. This command is just here to acquire it smooth to procure started with your CSV data.
You can find the entire set of parameters that csv2db provides in the ReadMe file as well as the User's Guide. I hope that csv2db will wait on some folks out there procure their CSV data into their database easily. Bug reports, enhancement requests, ideas, comments, etc. are sum welcome. Just submit them as issues on GitHub, preferably.
And, of course, please feel free to spread the word!
