This is very similar to a (2 and half year) old query:

How can I get changes from the logical diagram to the physical diagram without deleting the physical diagram. I want to update an existing physical diagram with changes made to the logical diagram. Is it possible?

Furthermore, different people are working on different Logical Subject Areas. They generate their PDM's. How do they ensure that the shared tables in the different PDMs remain in sync (similar to logical level)?

as changes can keep occurring at the logical or physical level.

Any ideas on how you cope with this would be greatly appreciated.

My view of the PDM is that it is a snapshot representing a particular change event. All changes are made using the ERD model and a new PDM model created.

This means that the ERD includes implementation constructs and ceases to be a true logical model once the project goes live.

I have never found a good way to map between a rolling logical model and a rolling implementation model. If there is a case tool that does this effectively it isn't one I have used.
