Mapping Objects in a PDM

Object mapping is the ability to establish a correspondence between objects belonging to heterogeneous models and diagrams.

In a PDM, you can link physical and multidimensional objects for the following purpose:

Relational to relational mapping between physical objects to generate extraction scripts to populate a data warehouse with operational data
Relational to multidimensional mapping between physical and multidimensional objects to generate text files containing cube data to fill the OLAP database
