MediaWiki is the software that powers sites like Wikipedia, Ubuntu Help Wiki, and many others.
In my spare time, I’ve written a patch to add IBM DB2 support to the development trunk. Hopefully, it will be added to the official source soon.
In the meantime:
- add_ibm_db2.diff — changes to existing files against r43499 of the trunk
- includes/db/DatabaseIbm_db2.php — Database API
- includes/SearchIBM_DB2.php — primitive search module
- maintenances/ibm_db2/tables.sql — database definition
There is a very good reason for the filenames.
This is all under GPL, so don’t look at it if you work on closed-source wikis.;-)
