The core component is the "data server". DB2 Express-C data server is available for 32 and 64-bit Windows & Linux as well as Linux on Power (for deploying on System p and System i servers). If you will be installing DB2 Express-C server on Linux and want to use languages other then English, you will also need to download and install the DB2 National Language Package.
DB2 Express-C data server's functionality can be extended to provide very fast searches of the text information stored in DB2 by installing DB2 Net Search Extender on the DB2 Express-C data server. Download and install the DB2 Net Search Extender if your applications demand fast searches of large volumes of text information stored in the DB2 Express-C server.
DB2 Express-C provides full enablement for industry standard web services based on SOAP and XML. This allows you to access data stored in the DB2 Express-C server as a web service. DB2 web services require an application server for deployment. This application server can be installed on the same server as the DB2 Express-C server or on a separate server. You can use IBM WebSphere or Apache Tomcat to deploy these services. In addition, DB2 Express-C provides DB2 9 Embedded Application Server a no charge web application server that can be used for deploying DB2 Web Services.
DB2 Express-C also provides DB2 Developer Workbench, a full function Integrated Development Environment based on Eclipse. If you plan to build SQL scripts, stored procedures, user defined functions or XML Queries, download the DB2 Developer Workbench.
Applications developed for DB2 often need to be deployed to client workstations or application servers. To enable these client workstations and applications servers to connect to your DB2 Express-C server you will need to install various drivers on these workstations and application servers. If your application is developed using Java you can download DB2 Driver for JDBC and SQLJ. Or if your application is developed using C or C++ and the ODBC interface, download and install DB2 Driver for ODBC and CLI. For applications developed using other programming languages or APIs, download and install DB2 9 Runtime Client. Or if you wan to have a full function client workstations with Command Line Processor and database administration tools, download DB2 Client.
The DB2 Spatial Extender allows you to store spatial point, line and polygon values in a DB2 table column and perform spatial queries using standard SQL. DB2 Spatial Extender is supported by applications from ESRI and MapInfo as well as open source projects GeoTools, GeoServer and uDig. More information.
