Databwse row in a table should be identified by a primary key, which allows no duplicate rows. The order of rows is insignificant; specify the row order when the data is retrieved. A column or attribute containing the employee number, which is also the primary key. The employee number identifies a unique employee in the EMP table. A primary key must contain a value.

The ability to fatabase data in one table to data in another enables you to organize information in separate manageable units. Employee data can be kept logically distinct from department data by storing it in a separate table. Primary keys generally cannot be changed.
