Q.2
(a) An Airline Check-in System is to be developed to allow passengers to
check in and get the boarding pass for flying. The baggage can also be
checked-in, which is optional. The check-in can happen by the counter
clerk or by the passenger using this system. The system should allow
individuals as well as group of passengers to check-in through the system.
The boarding pass can be issued through this system. Passengers below 4
yrs. need not have tickets. The airport also allows to provision for the
special needs of passengers like wheelchair etc. The system should also be
able to capture the fact that the baggage for a passenger is screened by
security. Identify Use Cases for this system. Draw Use Case Diagram for
the above scenario.
