RELATIONSHIP trigger modules execute the update, that is, set the foreign key to null, to implement a DISASSOCIATE or TRANSFER in an action diagram. They also identify more processing that is required, based on the ERD rules and the type of action that is requested, a DELETE, DISASSOCIATE, or TRANSFER. A call to the appropriate ENTITY trigger module processes additional deletions.
The RELATIONSHIP trigger module manages the delete or disassociate of the link records that are required for many-to-many relationships. One RELATIONSHIP trigger module exists for each relationship.
To ensure the uniqueness within the model, the default member name for RELATIONSHIP trigger modules is an F followed by a number. CA Gen assigns default names when the entity types are added on the workstation, or when foreign key linkage is added to a data record as the relationship is transformed. To use specific names, specify member names before generation.
