I am using EJB with PostgreSQL. PostgreSQL supports some types of
polymorphism -- tables can inherit attributes from parent tables, and
queries can even be issued against "all tables which inherit from X". I
believe that some other databases such as Oracle support similar
functionality.

My question is -- from entity beans (preferably CMP, although BMP would
be ok), can I take advantage of this functionality in an elegant and
designed way? Or is EJB just not there yet with respect to this kind of
OO database functionality?

Thank you,

Bryan
