Chapter 7 Linking and Synchronizing Models in PowerDesigner
You can map objects when you want to establish a correspondence between objects belonging to heterogeneous models and diagrams. Object mapping creates a structure for data movement and transformation: data comes from a data source and is loaded in another database or model.
You can use the mapping editor to easily create mappings between models objects using drag-and-drop or specific tools. If you drag a source object and drop it on a target model (without defining the target object of the mapping) a new object is automatically created in the target model, it is actually a shortcut of the source object.
For more information on the mapping editor, see "The Mapping Editor" chapter.
