Data Source Checks

PowerDesigner provides default model checks to verify the validity of data sources.

Check	Description and Correction
Data source name and code uniqueness	Data sources 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 model	A data source must have at least one model in its definition. Manual correction: Add a model from the Models tab of the data source property sheet Automatic correction: Deletes data source without a model
Data source containing models with different Object Language or DBMS types	The models in a data source represent a single set of information. This is why the models in the data source should share the same DBMS or object language. Manual correction: Delete models with different DBMS or object language, or modify the DBMS or object language of models in the data source Automatic correction: None
