Add Relationship Actions

A relationship action is an action used to manipulate pairings of stored entities. Relationship actions maintain the relationship between the entities in an entity action.

Adding relationship actions to the Action Diagram consists of the following activities:

• ASSOCIATE entities
• DISASSOCIATE entities
• TRANSFER relationships

Relationship actions appear as clauses in CREATE or UPDATE action statements. Specifically, ASSOCIATE can appear as a clause in either CREATE or UPDATE action statements. DISASSOCIATE and TRANSFER can also appear as clauses in UPDATE action statements. ASSOCIATE, DISASSOCIATE, and TRANSFER can also appear as standalone relationship actions.

Note: When ASSOCIATE, TRANSFER and DISASSOCIATE appear outside of CREATE and UPDATE statements, all appropriate READS must be performed to populate the entity action views involved.
