Rоn Swаnsоn hаs creаted custоm statues made out of wood for over ten years. For every sale, he obtains the customer's name, address, and a description of the statue. Ron has hired you to construct an accounting information system (i.e., database) which he wants modeled after his paper records. As you look over the records, you notice that some customers have the same customer number. For example, Rob Farnsworth, Bob Farnsworth, and Sam Farnsworth all have the same customer number. Ron says they have the same customer number because they all live at the same address. You explain to Ron that, in the customer data table being created, every customer will be identified by a unique customer number, the table's primary key, that can not be left blank. If a customer number is left blank, the customer data table would no longer enforce the _______________________.
