You must implement a library which exposes this interface. > btw, TDataSet is not part of dbExpress. No. It's part of the VCL. It's available in FPC as well. dbExpress has 2 parts: - A VCL part - a TDataset Descendendent. - A driver, which exposes a strictly defined interface. The driver can be written in any language. > > I also looked at Qt's database classes and I see a strong resemblance to dbExpress's > (including class and method names !) I suspect that this is because Borland and Troll Tech cooperated on this matter, and I would not be surprised if Troll Tech used Borland's design :-) > > > > > FPC supports both COM and CORBA interfaces - right ? > > > > I wouldn't have thought so. Delphi does it via compiler magic. > I think fpk told me so on #fpc . An interface is a construct independent of COM or CORBA. It's just a set of methods. Delphi does allow you to use COM methods transparantly via interfaces. In principle, the same should be true for FPC.
