I believe the previous post has it spelled out correctly: If one is looking for just a data modeling tool, then I'm sure that ERwin is the best.

However, one thing DBA's and Data Modelers always forget is: The reason to create a data model, is that an application will be built on top of it.

That's where Designer/2000 is a better tool. Its been a while since I used ERwin, but I doubt it integrates the database constraints with client- side constraint validation. I doubt ERwin uses data model information to build LOV's (and validation of) in the client app. I also doubt that ERwin has any support for constructing API's to protect database tables from improper access.

So, if you just want data modeling, then pick a best-of-breed data modeling product. If your a developer like me, then you should look closer at the integrated CASE products.
