Course:Computer Science
Institution: Meru University Of Science And Technology question papers
Exam Year:2013
TIME: 2 HOURS
INSTRUCTIONS: Answer question one and any other two questions
QUESTION ONE – 30 MARKS
Meru University is to introduce a new system for student registration where a student registers for course units during a specified registration period. To register, a student must see their course advisor who must approve each course that the student has selected. The advisor will use the registration system to determine if the student has met the course pre-requisites, is in good academic standing and is therefore, eligible to register for the course. If the advisor approves the course, he/she enters the students number and course ID into the course registration system. The course description will automatically display. The system will then check for schedule conflicts before saving the registrations. A bill for the course will automatically print in the bursar’s office and the student should proceed to that office to pick it up.
Schools/Departments can use the system to check enrolments in their programmes, get a class list, check a student’s transcript and look up a student’s contact and any other student information. The registrar can use the system to enter new courses for an upcoming semester, cancel a course and check conflicts in courses/schools. The admissions office uses the system to add new students. The admission department uses the system to report on students who have dropped out, update student information and check fulfillment of graduation requirements for students planning to graduate.
Use your knowledge of software development to answer the questions below:
Use cases are a requirements discover/elicitation tool that a software engineer can use to determine requirements for a system. For the student registration system described:
