Data integrity refers to the accuracy, consistency, and reliability of data that is stored in the database. Both database designers and database developers are responsible for implementing data integrity within one or a set of related databases.
Referential integrity is a system of rules that ensure relationships between rows in related tables are valid and that you do not accidentally delete or change related data. When referential integrity is enforced, you must observe the following rules: You cannot enter a value in the foreign key column of the related table if that value does not exist in the primary key of the related table. However, you can enter a null in the foreign key column.
