I haven't even heard of SAPDB, but as with any database I guess what
matters is what you intend to use it for. I like Firebird, and we switched
our production database from IB to FB with version 0.9.4. I doubt many - if
any - databases can equal Firebird in stability at such an early stage in
its life cycle. We do not have any big projects ourselves - all we do is
register every cancer in Norway and do research on it. I think our main
database is about 1Gb, and I'm sure you'll find many with much bigger
databases, as well as databases which has to be live 24/7 (whereas for us,
it doesn't matter whether you register a cancer today or in one weeks time).

You do not say what is your business - and if your working in areas where
everything must work at all times (e.g. with aircrafts or nuclear plants) I
think you may be dealing with an area where Firebird is untested. If not,
the main reason I can think of in convincing your boss is that IBO is the
yearly winner of the 'Best Database Connectivity' Award from Delphi
Informant and that it only works with Interbase and Firebird.

Hopefully you'll get plenty of more answers,
