Yea our tables don't have any relational information set up, they are coming from and AS400 into SQL server and no one really knows how they tie so we are trying to setup a road map per say. If you have any ideas or suggestions on where to look to see how to set up the diagrams without effecting the actual data or tables I would sincerely appreciate it. Otherwise I may look at the ERwin to see what it can do and cost etc...
