Pennyless Developer asks: "So the time comes when one must design a brand spankin' new database schema. You want to use an Entity-Relationship diagramming tool with hopefully some automatic schema generation tools, but do not have much money to purchase anything like Rational Rose. Like a true geek well versed in OSS, you head off to scan sourceforge, freshmeat, and google. But alas, it appears no such applications exist in the OSS world, at least none beyond the planning stage. The question I pose is this: What useful, OSS/Free/Cheap ERD applications have you found and used? Or do developers do all their ERD work under an evaluation period of commercial software?"
