MySQL is a lot better than it was 10 years ago, but it still has a
habit of playing fast and loose with certain types of input
validation, silently discarding or changing certain types of data
and allowing invalid queries. It still has a brain damaged query
optimiser and the query analyser is next to useless compared to
many other databases. Their clustering is still a poor mans
solution, and doesn't scale to large databases. That said, we still
use it for several, non WO, systems and provided you know the long
list of caveats and avoid the issues they pose it works very well
as a basic db.
I really, really like PostgreSQL, it has almost everything you
could possible need, save for a few very advanced features only
available in top dollar systems, the query planner is extremely
good, and the various inbuilt analysis features are very useful,
but what it really lacks is a solid, two phase commit, clustering
solution.
FirebirdSQL is actually extremely good for something with such a
small footprint, however it lacks deferred constrain validation,
which makes it a little difficult to utilise constraints fully with
WO, but there are people using it with WO. It also lacks a non-
commercial clustering solution. It is also very resilient to
crashes and unexpected shutdown. I would rank it higher than MySQL.
Interesting. I used Interbase years ago with Delphi and I really
liked it. MS SQL also also deferred constraint validation (which is
NOT a vote for MS SQL!!!). I added a DB context class to Wonder that
orders the operations to maintain FK containt validity. So far it
has handled everything I have thrown at it. I don't see why it would
not work with Firebird as well.

Frontbase is just rock solid, a perfect match for WO. It's
clustering is the best I have seen. Unfortunately it flies below
the radar of most people, but then so does WO.
Until postgresql gets a solid clustering solution, frontbase comes
out in front in my opinion.
None of them are bad choices.

You know, I have thought this same thing of MySQL for years, but I
think it's because I'm evaluating it based on its feature set from
1998 and not giving it a fair shake. I've read a lot of stories
on, for instance, highavailability.com about huge sites that use
it. I'm not too keen on the restriction that clustering is in-
memory only, but it actually seems like a legitimate database
these days (ONLY with InnoDB). It's on my list of things to
evaluate more fairly :)

I am with Mike on this. If you just need free, FrontBase is hard
to beat. If you must have open source, PostgreSQL. MySQL has
some nice features, but... I dunno, it is still MySQLToy to me.

I prefer FrontBase ... It's trivial to setup, runs very well,
and it's free. MySQL and PostgreSQL are obvious other choices
as well.
