AutoParts Warehouse

AutoParts Warehouse is a small auto parts supplier with locations in several Midwestern metro areas. The business is based on the idea of discount prices for auto parts that are always in stock or can be delivered within hours. The owners have decided to computerize their operations to allow them to better track their business and manage their inventories for just in time deliveries for sales. Data to be gathered for each customer sale includes invoice number, date, parts number, cost, retail price. Customer data is collected that includes basic contact information and vehicles owned, which includes vehicle make and model. For parts that have to be delivered to the store to fulfill a customer purchase, a transfer request is created. Data associated with these transfers include tracking number, invoice number, date, parts number, origination location (store or warehouse) number, destination store number.
