    Bob's Bookworld is a wholesale supplier of textbooks to college bookstores. The company would like to develop a database to track customers orders. Textbooks are uniquely identified by an ISBN printed on their back cover and are also characterized by title, author name(s), subject and price. College bookstores are each assigned a unique Customer ID and are also characterized by their store name, address, and phone number. Each store is uniquely identified by an order number and also records the date the order was placed, subtotal, sales tax amount and order total. Orders can include multiple copies of a single textbook and/or different textbooks. For each textbook ordered, the quantity ordered should be recorded.
