You are asked by the University to advise on the development of an object-oriented system to handle its examination process. The university offers several study programs, and each program is made of a number dn of courses. A minimum of two exams, midterm, and final term are required for each course in one semester. The university offers two semesters of equal duration annually. An Exam Coordinator has to assign the venues (exam halls) needed to hold the examinations. Students lists are displayed at the assigned venues along with the date and duration of the exam. The students can take exams for the courses they have registered only in the department they have attended. Once these are confirmed, the Exam Coordinator will allocate invigilators to each venue of the examination. After the examination is completed, one of the Invigilators will collect exam sheets (papers) and confirm that the number of sheets matches the number of students in the venue. The Invigilators will submit the papers to the Exam Coordinator. The Exam Coordinator will then send the papers to the appropriate Examiner, who will mark the papers. Students who fail to attend the exams without a valid reason can attend the next examination with some financial penalty. Once marked, the Examiner will return the papers to the Exam Coordinator, who will generate a list of results for the examination section. The Exam Coordinator can authorise the payments to the examiners, invigilators, and other refreshment and stationary costs from its budget. Analyse and explain (in your own words), with the help of a UML class diagram, as to why it is advantageous to use object-oriented programming for this problem, listing down the reasons that justify your selection of the classes, the relationships between the classes, the type and access modifiers of the variables and methods.

Question
Transcribed Image Text:You are asked by the University to advise on the development of an object-oriented system to handle its
examination
process. The university offers several study programs, and each
program
is made
of a number
dn
of courses. A minimum of two exams, midterm, and final term are required for each course in one semester.
The university offers two semesters of equal duration annually. An Exam Coordinator has to assign the venues
(exam halls) needed to hold the examinations. Students lists are displayed at the assigned venues along with
the date and duration of the exam. The students can take exams for the courses they have registered only in
the department they have attended. Once these are confirmed, the Exam Coordinator will allocate invigilators
to each venue of the examination. After the examination is completed, one of the Invigilators will collect
exam sheets (papers) and confirm that the number of sheets matches the number of students in the venue. The
Invigilators will submit the papers to the Exam Coordinator. The Exam Coordinator will then send the papers
to the appropriate Examiner, who will mark the papers. Students who fail to attend the exams without a valid
reason can attend the next examination with some financial penalty. Once marked, the Examiner will return
the
papers to the Exam Coordinator, who will generate a list of results for the examination section. The Exam
Coordinator can authorise the payments to the examiners, invigilators, and other refreshment and stationary
costs from its budget. Analyse and explain (in your own words), with the help of a UML class diagram, as to
why it is advantageous to use object-oriented programming for this problem, listing down the reasons that
justify your selection of the classes, the relationships between the classes, the type and access modifiers of
the variables and methods.
