Hi all!

I am new to this forum and to Oracle Designer 9i. Well my question is:

I am building ERDs for my database using ERD diagramer in Oracel9i Designer. I would like to extend my designing with object oriented features such type and subtypes. Besides using the UML modelling tools is there any other ways to model type - subtype relationships in ERD digramer. It seems to support just binary relationships.

Any suggestions is appreciated.
Thanx in advance.
