ODMG produced an object model that specifies a standard model for the semantics of
database objects. The model is important because it determines the built-in semantics that
the OODBMS understands and can enforce. As a result, the design of class libraries and
applications that use these semantics should be portable across the various OODBMSs that
support the object model (Connolly, 1994).
