Delphi5<--> Pervasive Workgroup 2000 (Btrieve 7.5)

Hello,  

Anybody with experience in the environment Delphi 5+Pervasive Workgroup
2000 (Btrieve 7.5)?  

The app has 4/5 users. It is necessary to have experience
to be able to evaluate the performance, the level of security, the power of
the SQL,
the stability, the recovery capacity in front of breaks,...  

The price is an obvious advantage in front of other databases, but, which
are the disadvantages?

I would thank information of a document with the comparison Pervasive vs.
Paradox, Access,...

Thanks in advance,
