Exercise 25

Jean & Joan Cosmetics has a complete line of beauty products for women and maintains a computerized inventory system. An eight-digit product number identifies inventory items, of which the first four digits classify the beauty product by major category (hair, face, skin, eyes, etc.) and the last four digits identify the product itself. Identify as many controls as you can that the company might use to ensure accuracy in this eight-digit number when updating its inventory-balance file.
