Chapter 6 Working with PDMs
You create a data source to define where (in which database) data should be extracted in order to be transferred to another database.
When you define a data source, you have to declare physical data models in the list of data source models. A data source can contain several models, you can select the source models among a list of models opened in the current workspace. All the selected models represent the same database that contains operational data.
A model can contain several data sources.
When you use a single PDM to design an operational, a data warehouse, and an OLAP database, the PDM is its own data source. In this case, you can use the Rebuild Cubes feature.
For more information on the Rebuild Cubes feature, see section Rebuilding Cubes.
