Database Design/SQL Editor Tool

Hi there, I did some search and the only thing that found is SQLEditor which for $69 is rather expensive.

All I need is to be able to model database entities (tables,views) in entity diagrams and import/export SQL for them. (SQLEditor is doing this, though it can't handle views)

Freeware is preferred but not necessary.

It doesn't matter.
As long as it exports ANSI standard SQL.

It doesn't have to connect to a db server or anything. Just a modeling tool really!

Sorry for the bump, but maybe my post didn't get as much attention in favour of the iPhone

I would really appreciate any feedback on this as I haven't been able to find anything by searching the forum so far.

Thanks!

PS. To give you an idea, in Windows I was using DDT
