Chapter 9 Working with Data Models

Data source checks (PDM)

The following PDM model checks are made on data sources:

Check Description and Correction
Data source name and code uniqueness Data source names and codes must be unique in the model.

Manual correction: Modify the duplicate name/code

Automatic correction: Appends a number to the duplicate name/code
Existence of physical data model A data source must contain at least one physical data model in its definition.

Manual correction: Add a physical data model from the Models tab of the property sheet of the data source

Automatic correction: Deletes data source without physical data model
Data source containing models differing DBMS types The models in a data source should share the same DBMS since they represent a single database.

Manual correction: Delete models with different DBMS or modify the DBMS of models in the data source

Automatic correction: None
