An airline flight monitoring system must notify several other systems when a flight’s status
changes. All of the systems are written in the Java programming language and located on the
same local area network. One of these systems, the crew scheduler, must receive all flight status
changes. If the crew scheduler system is down, it must receive all status changes when it restarts.
