I’m glad to report that we’ve just released a new version of DB2, namely DB2 Express-C 9.7.2. This version — of what is arguably the most advanced hybrid database system in the world — is (as usual) absolutely free to develop with, deploy in production, and even redistribute.
Unlike SQL Server Express which is limited to 10GB of data, there are no data limits with DB2 Express-C. This means no database size limits or any restrictions on the number of databases, connections, users, etc…
Oracle XE is even more restrictive than SQL Server Express and seriously insecure, having not been updated for a long time despite the presence of major security vulnerabilities. Unlike Oracle XE, DB2 Express-C uses the same core code as its commercial editions and is always kept up-to-date.
In case you are wondering, there’s no catch. We generate our revenue from affordable, but entirely optional, dedicated 24/7 technical support (a popular business model in the open source community). If you haven’t tried DB2 Express-C before or you currently have an older version installed, consider getting the latest one here and taking it for a spin.
Some of the improvements and features of this FixPack 2 edition include:
Support for the MySQL syntax for LIMIT and OFFSET. This greatly simplifies the process of getting existing applications to work with DB2.
The IBM Data Server Provider for .NET has been enhanced in several ways that may help you with application performance, data server compatibility, and simplifying application development.
Both Rails 3 and Django 1.2.1 are supported from out of the gate thanks to our IBM provided, open source drivers and adapters.
Enhancements made to user-defined functions (UDFs), which now support both default values for parameters and named arguments.
The RESTORE command can now be used with the TRANSPORT option to copy table spaces and SQL schemas as a set from a database backup image to another active database.
Auditing improvements now allow replay of past database activities.
