I teach a class at the University of Washington, and in that class I have the students create a few Entity Relationship Diagrams (ERDs). I’m still looking for a decent tool to do that, since the only ones I know that do a good job are WAY too expensive. Visio is about the best I’ve found for them, and one of the students sent me a link he found for learning and using Visio – very nice. Thanks, Rod!
By the way, Visio Team – it’s a crime that I have to install all of Enterprise Architect just to get an ERD tool. Break it out of there into it’s own SKU!
