What is Types of Integrity Constraints in DBMS about?

Integrity constraints are rules used to maintain data quality by ensuring data is inserted, updated, and processed without affecting integrity. They guard against accidental database damage. There are several types of integrity constraints: domain constraints define valid value sets for attributes; entity integrity constraints require primary keys cannot be null; and referential integrity constraints require foreign keys in one table must match or be null in the referenced table
