Referential Integrity

Referential integrity rules are part of the definition of relationships between enterprise objects, just like joins between database tables. These rules work to maintain the integrity and consistency of the data that gets committed to the database. Enterprise Objects supports these referential integrity rules:

• optionality

• delete rule

• owns destination

• propagate primary key

These rules are described in more detail in EOModeler User Guide. In most cases, you configure referential integrity rules in EOModeler. Your enterprise object classes have no direct knowledge of the referential integrity rules of their relationships. These rules are characteristics of EORelationship objects of which individual enterprise objects have no direct knowledge. This means that you need to be concerned with referential integrity rules when designing data models but not when adding custom logic to enterprise object classes.
