Question 3 [20]
Consider the case study that follows and answer subsequent questions.
A passenger arrives at the airport, and goes to the airline desk to check-in. The passenger presents
their ticket and passenger services will check the validity of the ticket. If the ticket is valid, the airline will
produce a boarding pass, giving a passenger permission to enter the restricted area of an airport and
to board the airplane for a particular flight. Otherwise the passenger is not allowed to fly, and referred
to booking/reservation services.
The boarding pass identifies the passenger, the flight number, the seat number, the date and scheduled
time for departure.
While the passenger is boarding the airplane, simultaneously the passenger’s luggage is loaded (or
checked-in), into the airplane by the airplane staff, organized by the luggage number. Some passengers
ONLY have hand luggage, and therefore their luggage is not loaded as the luggage of the other
passengers.
After the passengers boarded the plane, the air traffic controller will give the pilot instructions to get
ready for take-off and to move the airplane to a certain runway or ‘taxing’ the airplane for departing
procedures.

Question 5 [20]
Use the scenario that follows to answer Question 5.1.
My small vehicle/car repair shop, consists of two offices, an electronic workshop and two repair
workshops. I or the shop employs many employees, and an employee works only for my shop. A job is
done by many employees, and an employee performs many jobs. This relationship creates a challenge
for me when I must analyze their working hours. I would like to have working hours as information of
the employee as well as information for jobs done.
Some of the jobs are done by engineers, and an engineer is assigned to many jobs. The engineers are
either full time engineers or part time engineers. The following data should be stored about each
engineer: Engineer number, Engineer name, Professional No, Tel number. For full time engineer’s
Annual salary is also stored, while for part time Hourly rate and Hours worked are stored.
