Primary Key

A Primary key is a unique identifier of a table, having a different value in each field, for example a column of customer numbers. A candidate key is a unique identifier that could be designated as the primary key. A foreign key is an attribute or a column in a relation that is identical to a primary key in another relation. The term "key" can also be defined as a method of entering data from a keyboard keyboard analogous with typing on a typewriter.

From Ellen Thro, "The Database Dictionary", 1990.

We use primary keys for data tables to ensure the highest possible data integrity. Primary keys help avoid deadly data corruption that can destroy a database and render it unusable.

This information is important for your Access programmer in the database development cycle and every database programmer should utilize this techniqu in database programming. A professional database developer always uses primary keys, including our Microsoft Access programmer team.
