Choose a candidate key that incorporates part of the table name within its own name. For example, a candidate key with a name such as SALES INVOICE NUMBER is a good choice for the SALES INVOICES table.

Examine the candidate keys and choose one to serve as the primary key for the table. The choice is largely arbitrary—you can choose the one that you believe most accurately identifies the table’s subject or the one that is the most meaningful to everyone in the organization. For example, consider the EMPLOYEES table again in Figure 8.5.
