Does anyone know of a simple ERD tool that would help me do data models? Something cheap or free and basic? I'm learning on my own with books and practice projects. Have Visual Studio 6 Ent. I'm new to this so its all about the concepts for me at this point and I'm attempting to work out data models for 2 projects. The database designer tool in VFP is cool but its a little more advanced than I need at the moment.

Hewlett Packard has a software tool package called DOME that has a nice data flow modeler. I'm looking for something comparable for er diagrams. Any ideas? Thanks
