If your DBMS supports it, PowerDesigner allows you to base tables on abstract data types (ADT), where the table uses the properties of the ADT and the ADT attributes become table columns. To link a table to an ADT, open the table property sheet to the General tab, and select the ADT (of type Object, SQLJ Object, or Structured type) in the Based On field.
For detailed information about working with abstract data types, see Abstract Data Types (PDM).
