What is a referential integrity in a database?

Referential integrity refers to the relationship between tables. Because each table in a database must have a primary key, this primary key can appear in other tables because of its relationship to data within those tables. Referential integrity is the logical dependency of a foreign key on a primary key.

What are the results of setting referential integrity?

In simple terms, ‘referential integrity’ guarantees that the target ‘referred’ to will be found. A lack of referential integrity in a database can lead relational databases to return incomplete data, usually with no indication of an error.

Why is it important to maintain referential integrity in a database?

When do you add foreign key rules to referential integrity?

Additional foreign key rules may be added when setting referential integrity, such as what to do with the child rows (in the Orders table) when the record with the PK, part of the parent (Customer), is deleted or changed (updated).

Which is a constraint of referential integrity in the PK?

The referential integrity constraint states that CrsCode in the Class table must match a valid CrsCode in the Course table. In this situation, it’s not enough that the CrsCode and Section in the Class table make up the PK, we must also enforce referential integrity.

Why are integrity constraints important in a DBM?
