Design a database $($ER diagram$)$ for the 'Pizza on the Run' company that delivers pizzas. Each pizza on the menu has a unique number, and the database should store the kind of base used $($crispy or pan$)$ and the price. Each pizza includes several toppings. Each topping has a unique code, name and price. The database stores information about customers. A customer has a number $($unique$),$ name $($first and last$),$ payment type $($cash or credit card$),$ email, phone and address. Information about employees includes unique employee number, name $($first and last$),$ phone, and address. An employee may be responsible for a single vehicle. Each vehicle has a unique registration number, type, and description. A customer makes orders. An order has a unique number, total price, and status. An order contains one or more pizzas. Each order is processed by an employee at a specific date and time. Information about the employee who delivered the order and the time of delivery is also stored.
