The Acme Airline Company has a fleet of small planes that can be chartered by customers to fly either
passengers or cargo across the country:
a CUSTOMER may book zero or more CHARTERS and each CHARTER must be booked by one
CUSTOMER
an AIRCRAFT may be used for zero or more CHARTERS and each CHARTER must use a single
AIRCRAFT
a CHARTER will have one or more EMPLOYEES on the flight and each EMPLOYEE may fly on zero
or more CHARTERS
Since the relationship between CHARTER and EMPLOYEE is many-to-many, use a composite
entity called CREW to break it up. A CHARTER will have one or more CREW members and each
EMPLOYEE can be on zero or more CREWS
for a CUSTOMER we need to store the ID, name, address, phone number, and current account
balance
for a CHARTER we need to store the ID, date, destination, distance flown, hours flown, gallons of
fuel used, and quarts of oil used
for an AIRCRAFT we need to store the ID, manufacturer, name, and number of seats
for an EMPLOYEE we need to store the ID, name, address, phone number, title, date of birth,
and hire date
