What is the significance of a cascade delete constraint in database design?
- It allows deletion of a parent record even if related child records exist
- It automatically deletes all records in a table when a deletion occurs in a related table
- It enforces referential integrity by preventing deletion of a parent record if related child records exist
- It is not a valid constraint in database design
A cascade delete constraint in database design ensures referential integrity by automatically deleting related child records when a parent record is deleted. This helps maintain consistency in the database.
