Final answer:
Integrity rules are specified and stored in a database management system (DBMS) to maintain the accuracy and consistency of data.
Step-by-step explanation:
Integrity rules are specified and stored in a database management system (DBMS).
In the context of databases, integrity rules are used to maintain the accuracy, consistency, and reliability of the data stored in the database. These rules are defined and enforced at the database level, allowing the DBMS to automatically check the data and prevent any violations of the rules.
For example, a common integrity rule is the primary key constraint, which ensures that each record in a table has a unique identifier. This rule specifies that the primary key column cannot contain duplicate values.
