MFC is a framework (and a bad one at that). It has lots more functionality than just database functionality. And the database functionality provided is not OO.

When using ObjectStore (am not a fan, BTW), I find that the only 'database' functionality needed is:
- Creating objects in database in stead of memory E.g.: New( Class, Database ) in stead of New( Class ) - Beginning/ending transactions
- Running indexed queries using same object method call syntax as host language
E.g. "Objects | Class->Method1->Method2->Attribute = Value"

How do you do it in COBOL+SQL?
