Top-Down: Mapping Classes to Tables

PowerDesigner provides default transformation rules for generating physical data models from object-oriented models. You can customize these rules with persistence settings and generation options.

  1. Create your OOM, and populate it with persistent classes (see Entity Class Transformation), inheritance links and associations etc, to define the structure of your model domain.
  2. Select Tools > Generate Physical Data Model to open the PDM Generation Options dialog.
  3. On the General tab, specify the DBMS type and the name and code of the PDM to generate (or select an existing PDM to update).
  4. Click the Detail tab and select the O/R Mapping checkbox. You can optionally also specify a table prefix that will be applied to all generated tables.


  5. Click the Selection tab and the select the OOM objects that you want to transform into PDM objects.
  6. Click OK to generate (or update) your PDM.
