Final answer:
The integrity rules component of a data model defines the boundaries of a database, constraints, and access methods.
Step-by-step explanation:
The integrity rules component of a data model establishes the boundaries of a database, specifies constraints on the data, and defines access methods.
Integrity rules ensure the accuracy and consistency of data within a database. They enforce various constraints such as uniqueness, referential integrity, and data type restrictions. For example, a rule may enforce that no two records in a table can have the same primary key, or that a foreign key must match an existing record in another table.
By defining integrity rules, database designers can maintain the integrity of the data and prevent inconsistencies or errors. Access methods, on the other hand, determine how data can be retrieved and manipulated efficiently.
