Hi all, thanks for all the replies, quite helpful.
I haven't gone AWOL, whatever that means, just been busy.

We still haven't decided what database to use, mostly because both teams would really like to stick with 'their' database, and none are really experts, which is why I turned to the users of this board, among other people.

My team would like to use MySQL, simply because we've never used Firebird and therefore feel more comfortable developing in a MySQL environment. The same probably goes for the other team and Firebird. However, if Firebird would indeed be the best choice, we'd ofcourse switch.

In this thread a lot has been said about MySQL, but not much has been said about Firebird. Could anyone give me some insight on how Firebird compares to MySQL?

None of the involved team are real database experts, so I thank you in advance for any further replies.
