Generating a PDM from an OOM
218
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 Description
New PDM Creates a new (default) PDM containing the objects translated
from the OOM
Updated PDM 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
To generate a PDM, you must indicate to generate one of the following:
