Software for drawing ERD and DFD?

[htdat]

I'm new to Fedora and Linux. Please introduce to me a good application on Fedora/Linux for drawing Entity Relationship Diagram and Data Flow Diagram. Thank you very much.

I think there is a dia package to do diagrams DFD included, but can not generate the code or scripts to implement in a database, at least 2 years ago when I used it. Take a look.

You can get a graphical package management as yumex, and search for available packages containing DFD word in their description.

You can check out this one http://www.graphviz.org/ and i believe they have redhat packages as well. As a second option you could go for http://freshmeat.net/projects/dia/
