Airline Reservation System: This database is for an airline reservation system. You will need to track the flights available. Each flight has a flight number, a destination city and a departure city, a date, a departure time, an arrival time, the total number of passengers booked on the flight and a total flight time (total flight time will not be stored to improve performance). Each flight is assigned a specific plane. A plane consists of an ID, a type (747, 777, 777X), and a maximum occupancy. Customers make reservations on flights. For each customer, we want to track a last name, address, and frequent flyer program type (gold, silver, copper). We also want to track up to 5 phone numbers per customer.
