I'm searching a free software to create entity relationship modells (for Mac OSX 10.6+).

Needed functions (mandatory):

  • draw model
  • add descriptions to relations

Needed functions (optional):

  • Chen's notation for entity-relationship modeling

Any ideas?

Thanks for your answer! The SQL Data Modeler is a pretty nice and handy tool. But I need the possiblity to add a description to relations and I was not able to find that feature using the software. (I missed that needed feature in my first question so I've made some additions) – road242 Apr 30 '11 at 18:45
@hkda150 Sorry I'm not aware of any other application which support the feature – Sathya May 11 '11 at 4:54

MySQL Workbench

Allows you to model SQL in an ER-like fashion. There's a standard community version, and a commercial version, which have a different feature set.

I'm not sure if it fulfills your needed functionality. – slhck Oct 11 '11 at 10:00
