An Object Relational Model (ORM) diagram visually represents the relationships between objects and entities in a relational database. It shows the connections between different tables, their fields, and data types in a simple, graphical way. Case Description Mama Mia's (MM) pizzeria offers pizzas, breadsticks, and Buffalo chicken wings for carryout customers only. Customers phone in the order and come by to pick up their order. When regular customers call MM over the phone, they are asked for their phone number. New customers must provide this information before placing orders. Once the order is taken, the tax and order total is computed. The order is then printed and submitted to the kitchen, where the order is prepared. A receipt is printed and given to the customer. Payment from the customer should be in check or cash only. Customers may provide coupons. Use EdrawMax to create similar ORM diagrams.
