There's been some attempts at DB objects, but none that actually got
completed.  I believe everybody just use UML, which is kind of a kludge.

The UML objects are the most complex objects by a longshot.  Don't expect
to be able to do everything in RDBMS with shapes.

There's some on the Dia Twiki

http://www.gnome.org/projects/dia/docs.html.

Good luck!
