entity relationship diagram software

hi all,

are there any good entity relationship design tools out there

and any that possibly export to rails migrations ???



Smart Draw is a good ERD application. It seems though that you are
more interested in some Enterprise Architect or Rational Rose
derivative. That, I'm afraid, I do not know much about.

I'll tell you this though, I find myself needing UMLesque like
approaches less and less with tools like pencil and paper and Ruby on
Rails that let me try and fail quickly and learn from my mistakes very
quickly.....plus it's so much more fun than state diagrams, use case
diagrams, and even ERDs.
