What are the implications of having a mandatory relationship in terms of data integrity?

- It doesn't impact data integrity
- It ensures that all related records are present
- It leads to referential integrity issues
Having a mandatory relationship ensures that all related records must be present, promoting data integrity. This constraint guarantees that every record in the "many" side is linked to a corresponding record in the "one" side, preventing orphaned or incomplete relationships.
