In fact, we would like to use the 3 connections for a 1 user licence. Because i think it is not possible any more with IB 7.0, i wanted to know if the fact to share a same connection is a good way. The only need i need is to access a same database with 3 different applications.
I can't be sure to use FireBird so, it is for this reason I ask you that for Interbase 7.0.

but concretely, in my case it's for 3 different applications so i don't use threads ? (sorry I'm not a specialist :-))

If you are talking about user licences. Then in IB 4.2, it was a 3
user licence for 3 connections. In IB 5.x, it was 4. In Borland's
commercial IB 6.x and 7.x, it is 1 user licence. If you need more
connections, you need to buy more user licences.

With IB 7.0 Borland states that the client library is thread safe, so
you wouldn't require to create a new connection for each thread(not
the same as an application). This is not the case for IB 6.x.

> Is it really possible with Firebird and how it works ?

It's not possible to share one connection with other applications, but
there's no limit to the number of connections to the Firebird server.
At the moment to my knowledge, the client library is not thread safe,
so you would require to create a new connection for each thread.

Probably Borland wanted a way to create some additional revenu compared
to previous versions.
