An interesting chart comparing MaxDB, MySQL, PG, FB, DB2, MSSQL and Oracle in
terms of usability with OpenCRX.

http://www.opencrx.org/faq.htm#db

I guess someone should tell them that MySQL is not so free. Also, some figures
in the chart just don't seem right. They also say that Firebird is "not
recommended for production use", but fail to explain why (as they did for
others). From my POV, it looks like they didn't test Firebird enough.
