Chapter 9 Working with Object-Oriented Models
The following OOM 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 have 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 |
| Differing DBMS types | The models in a data source represent a single database. This is why the models in the data source should share the same DBMS.
Manual correction: Delete models with different DBMS or modify the DBMS of models in the data source Automatic correction: None |
