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
