Hi: I am looking for a free ER-Diagram software for my own personal use. I have used ER/Studio (a commercial package) heavily before and I liked it. But I couldn't afford it now. Is there some kind of freeware there that people like? My requirements are 1. run on Microsoft PC 2. GUI Interface, so I can draw ER diagram to create tables and constraints 3. can "export" the diagram into Image file 4. can generate DDL script from the ER diagram. Thanks.
