Hi

I'm looking for some sort of database diagram tool, that can generate a ER diagram for a database in Chen's notation. I would much prefer a tool that can generate the diagram from a existing structure, if such thing is possible.

For some reason most tools available today doesn't seem to support Chen's notation.

+1  A: 

Chen's ER diagram DB notation is supported with Creately - http://creately.com

It cant generate it from existing source though.
