Importing a deprecated PDM logical model

Chapter 3 Building Conceptual and Logical Diagrams

Importing a deprecated PDM logical model

If you have previously created a PDM with the logical model DBMS, you will be invited to migrate to an LDM when you open it.

To open a deprecated PDM logical model:

Select File→Open and browse to the PDM logical model to open.

Click Open to display the Import Logical Data Model dialog:

Choose one of the following options:
- Convert the model to a logical data model – Note that only tables, columns, keys and references are preserved
- Change the DBMS target to "ANSI Level 2" and open it as a PDM

Click OK to open the model.

Restoring generation links to a converted LDM
A PDM with the logical model DBMS that had been generated from a CDM will retain its links to the source CDM when you convert it to an LDM. However, for any PDM generated from the old LDM, you will need to restore the generation links by regenerating the PDM from the new LDM, using the Update existing PDM option (see Linking and Synchronizing Models in the Core Features Guide ).
