Whatâs referential integrity?

The concept of referential integrity, and one way in which it’s enforced, is best illustrated by an example. Suppose company X has 2 tables, an Employee table, and an Employee Salary table. In the Employee table we have 2 columns – the employee ID and the employee name.

It literally means having wholeness of character, just as an integer is a whole number with no fractions. Physical objects can display integrity, too — if you're going over a rickety old bridge that sways in the wind, you might question its structural integrity.
