I use UML for data(base) modeling (see this post for a discussion on the suitability of UML for this task) but many many people (specially with a strong database babckground) still prefers to use the ER language or any of its variants for data modeling.

If you are one of them, I’m pretty sure you’ll find this very exhaustive list of data modeling tools interesting.

(by the way, we already referenced this site once before highlighting its free library of more than 600 data models )
