You have been asked to develop a Fingerprint Access System (FAS) to monitor and control the entry to and from a secure facility. A computer connected to fingerprint readers will electronically control entry and exit gates. Personnel wishing to entry or exit the facility will place a finger on a fingerprint reader at the gate, and the gate will be unlocked to let them through, if the fingerprint is valid. When the fingerprint reader scans the fingerprint, it will send its image to the FAS. The FAS unlocks the gate, logs an entry event for that particular person, and increments its occupant count. After the person passes the gate ( a sensor on the gate will determine that), FAS will lock the gate. In case the fingerprint fails validation, the system logs a failed entry event and does not open the gate. If the validation failed erroneously, an error recognition count is incremented. Security managers need logs showing all entries and exits and all failed attempts at entry or exit. They need to control the fingerprint recognition error rate (make it adjustable) Also, they need a report on all current facility occupants, and be able to find out whether a particular individual is in the facility. The Fire Marshall needs individuals to be able to leave the facility unimpeded (leave the gate open) during an emergency. Also, he needs emergency personnel to be able to enter a facility unimpeded during an emergency Draw the use case diagram and describe 3 4 use cases from the diagram, choosing them to demonstrate your understanding of includes and extends relationships.
