Ha! :-) Thanks Doc.
Is it possible to simulate an ER Digram using UML? There's an open source Visio clone named Dia, which has an add-on that will forward engineer a db design into DDL statements for a variety of databases - Oracle, Postgres, etc. Seems the method is to use UML diagrams as a proxy for ERs - substituting an Entity for a Class name. Looks a little strange.
