Generating a PDM from an OOM
Generating a PDM from an OOM
You can generate a PDM from a global OOM or from a package within the model. Limiting PDM generation to a single package is useful when different designers own packages of the same OOM. Designers can generate their packages independently from others. Generating a package results in an independent PDM .
You generate a PDM from a diagram in the model.
You can generate a PDM in two ways:
Generate
New PDM
Updated PDM
Description
Creates a new (default) PDM containing the objects translated from the OOM
Creates a default PDM containing the objects translated from the OOM that is then merged with an existing PDM. You can choose to update, delete; or add objects in the existing PDM (target model) based on modifications made in the default PDM (source model)
∃For more information on merging two PDM, see the chapter Comparing and Merging Models in the PowerDesigner General Features Guide.
Generating and updating a PDM
Generate new Physical Data
To generate a PDM, you must indicate to generate one of the following:
♦Generate new Physical Data Model
♦Update existing Physical data Model
You must indicate the following parameters when you generate a new PDM:
Model
Parameter
DBMS
Link
Local to the Model
Name
Code
Description
Database Management System definition (DBMS) for the resulting PDM
DBMS for the resulting PDM refers to the DBMS definition file stored in the DBMS library
DBMS for the resulting PDM is a copy of the DBMS definition file stored in the DBMS library
File name for the resulting PDM
Reference code for the resulting PDM
