Model Checks

PowerDesigner provides default model checks to verify the validity of models built on a schema.

Check	Description and Correction
Identifier uniqueness	Two or more objects cannot have the same identifier (ID). Manual correction: Give a unique identifier to each object Automatic correction: None
Undefined identifier	You must define an identifier (ID) for each object in the model. Manual correction: Define an identifier for each object Automatic correction: None
Shortcut code uniqueness	Two shortcuts with the same code cannot be in the same namespace. Manual correction: Change the code of one of the shortcuts Automatic correction: None
Undefined target namespace	You should define a target namespace to your model. Manual correction: Type a URI for the Target Namespace property in the Detail tab of the model property sheet Automatic correction: None
Missing namespaces	There should be at least one namespace defined for the model. Manual correction: Type a URI and a prefix in the Namespaces tab of the model property sheet Automatic correction: Adds the target namespace URI and a prefix "ns" followed by a number (e.g. "ns1")
