RELATIONSHIP Trigger Modules

RELATIONSHIP trigger modules execute the update (set null) of foreign keys to implement a DISASSOCIATE or TRANSFER in an action diagram. They also identify additional processing required, based on the DMD rules specified and the type of action requested (DELETE, DISASSOCIATE or TRANSFER). Further deletions are processed by calling the appropriate ENTITY trigger module. The RELATIONSHIP trigger module also manages the delete or disassociate of link records required for many-to-many relationships. One RELATIONSHIP trigger module exists for every relationship.
