Consider the folloiwng case study:

$($CLO$-2)(5*4=20$ marks$)$

Course Registration:

Students submit registration forms with their name, identification number, and the numbers of the courses they wish to take. For each form, the registrar verifies that each courses selected is still open by referencing the course file. The file distinguishes courses that are still open from those that have been canceled or filled. Subsequently, the registrar determines which of student's selections can be accepted or rejected. Then the registrar enrolls the student in the courses for which he or she has been accepted and updates the university's course file with the student name and identification number and recalculate the class size. If maximum enrollment has been reached, the course is closed. The enrollment process also updates the student master file with information about new student or changes in address. The registrar then sends each student applicant a confirmation$-$of$-$registration letter listing the course for which he or she is registered and noting the course selections that could not be fulfilled.
