1-3. Perfect Pizza wants to install a system to record orders for pizza and calzones. When regular customers call Perfect Pizza on the phone, they are asked their phone number. When the phone number is typed into a computer, the name, address, phone number and last order is displayed. If the name is not found the person will enter the information. Once the order is taken the total including tax and delivery is calculated. Then the order is given to the cook. A receipt is printed. Occasionally, special offers (coupons) are printed so the customer can get a discount. Drivers who make the deliver give the customer a copy of the receipt and coupon. Weekly totals are kept for comparison with last year's performance.

A commercial bakery makes many different products (each from several ingredients.) These products include breads, desserts, specialty cakes, and many other baked goods. Ingredients that are used in many products - such as flower, spices, milk - are purchased from several vendors. Sometimes many ingredients are purchased from a single vendor (sometimes in the same order), and other times a single ingredient may be purchased from many vendors. The bakery has commercial customers, such as schools and restaurants, that regularly place orders for several types of baked goods (sometimes in the same order.)
Draw a stable ER Diagram. Please draw the entities and their keys. Don't bother indicating non-key attributes. Create additional entities that you need to stabilize or complete the diagram, but don't imagine other entities that are not part of the situation.
