These days, everybody's talking about Oracle's attempts to buy MySQL and their previous purchases of Innobase and Sleepycat.
As I already mentioned earlier, I hope that Oracle will never gain influence on how MySQL evolves. MySQL is on its way to become a high end database system and so might - at least in some business areas - be a serious competitor of Oracle. What really turns my stomach upside down is the thought that MySQL could (in some people's minds, hopefully never in reality) become a lower-end alternative of something. MySQL should make it's way independently and never let any proprietary competitor gain any influence in any way.
However, what I would appreciate very much would be more co-operation among the Open Source database producers. A while ago, people from the major Open Source database systems have met to form the Open Source Database Consortium - that was in October 2005.
OK, that's not that long ago, but I hope that the ambitions to co-operate aren't over again. It was told that a website will be created at www.osdbconsortium.org. There's nothing to see except a "Just a web page" note. I haven't heard any news about this since October - I believe, it would be nice if MySQL, PostgreSQL, Firebird etc. could do some things together. That would certainly be more welcoming than any deal with a proprietary database vendor.
