Tool for creating relational model diagrams [closed]

Question

I'm looking for a free and simple tool for creating relational model diagrams.

All that i need is to be able to draw tables and fields and connect fields that are foreign keys to their referenced tables.

As an example I found this image on the net.

I don't need anything more: I want to keep schema simple and clean.

Thanks for your answers. However, a friend of mine suggested that I can use any vector graphics program. His advice helped me to found the beautiful "LatexDraw" editor. It's worth a check, especially if you care about printed quality.

Answer 1

Dia supports:

• Windows
• Linux
• OSX

Performs

• UML
• relational modeling
• and more (lots more)

I've used it for both UML and relational modeling with great success. I have heard the Windows version can be unstable, but I've never experienced this personally.
