Hi Dan,
Yes - same domain object. Otherwise you end up duplicating everything
and mapping from one inheritance hierarchy to another. The ORM tool is
taking care of all the difficult mapping from object to database so
your domain object can truly become an intelligent business object and
not an anaemic domain model [1] [2]
Hope this helps.
Cheers,
