Detailed Description

Db objects: DbSessionObj.

Description: Implementation independent part of a Database session object.

There is a ring of protection around the object. The object can only be accessed through its handle, the technology dependent code and the DbDatabaseObj object hosting the container. This should ensure proper reference counting and inhibit non existing references flying around.
