Hi G;
The OE application is just based on the original OE sample database from Sybase. If you open the Customer and/or Employee dialogs you will not only see a Master/Detail implementation - one in the same window and, one across multiple windows - they are also fully up-datable and use the DW/DS update manager to synchronize DBMS activities.
The "tabbed" Product dialog is also up-datable and uses similar techniques found in both the Customer and Employee dialogs mentioned above - which of course use the FC's services.
