Reference attributes are persistent attributes representing references to other persistent objects. To store the type of referenced object, you should assign a class identifier to the reference attribute. This identifier identifies the class of the referenced object and provides an implicit link to the storage location where the required entry is kept. Without this link, the system would have to search through all tables with GUIDs as primary keys.
