ASSIGNMENT 1
Perfect Pizza is a pizza delivery shop. They make pizzas only for home delivery. They have recently
designed a new database to track their sales. They use the customer’s telephone number for a Key
column in the Customer table. They are interested in households, not individuals. They need the street
address and zip code for the delivery. They deliver to only three zip codes 98001, 98002, and 98003.
With the zip code, they can fill in city and state information later, though they prefer to do it when
they enter a new customer. In the OrderDetail table, they store the price charged for two reasons:
First, it may be different than product price due to a discount or special allowance and second, it keeps
a historic record of the price. That way, if they change the price in the Product table, it doesn’t affect
the prices charged in past sales. Here is the entity relation diagram for the database.
