You want to design a database for a restaurant. Customers have email, name, phone, and password. Each customer can have several credit cards registered in the system, each credit card has a 16 digit number, an expiration date, a 3 digit number (CVC code), and the name on the card. The menu items have a short description, a long descriptioin and a price. Customers can place orders that have the date/time that they were placed, one or several menu items (for each menu item it also keeps the quantity), and the total price (summation of the prices of the items mutiplied by the quatity of each item). There are two types of orders: dine-in, or pick-up. In the case of pick-up orders the system must have the car make, model, and color of the person picking up the order, as well as a parking spot number. Dine-in orders have a tip. In addition, the system needs to know if an order has been paid or not. Draw a complete ER diagram. Your diagram must include ISA relationships.
If you need to make additional assumptions, please write them down.
