because TDM focuses mainly on physical structuring of databases, the feature of using Chen notation, which is used to build logical diagrams, to draw logical ERDs, is not available in the scope you would probably need and we aren’t planning TDM to go this direction in future.
We try to answer all kinds of questions as soon as possible, so if you want to ask anything else, don’t hesitate and post it here.
I hope you will find TDM helpful for your business.
