Hello all, I would like to find a good app that will allow me to create entity relationship diagrams. This would be what I would use it for now, but I would use it for any other situation where I might need to do diagrams for work in future. Export to PDF is a necessity, direct print from the app would be a plus but is not required. I know there are lots of apps out there, so I was hoping some of you have tried a few and had suggestions. Omni group has some very attractive looking apps, and I have owned and enjoyed their desktop software in the past. Just want to see if there are less costly alternatives out there. I'll bite the bullet, price-wise, if needed, but want to tap into the experiences of you folks first.
