I am looking to replace interbase with firebird but having some
questions/issues on what I should install.

I have 2 applications one application connects to a gdb database on a
server the other is a stand alone application that is used outside of
the office (no server/network connection)both are installed on the
same machine. Right now I install IB server on the server, and IB
desktop on the client. By installing the desktop version I can
connect to the server's db AND I can run my other program stand alone.
What version of Firebird is compatable to IB desktop edition?

Also both applications server and stand alone do make multiple
connections to databases simultaneously. What are firebirds
limitations?

Thanks
