The following is the partially designed ERD diagram that will be used for the student project management system. The staff must be a supervisor role in order to propose projects for students. A supervisor can propose many project. Each project can be only assigned to one student. The project done by the student will be evaluated by the respective supervisor based on execution, report writing, coding and presentation components, the total score represent the sum of these four components. There are two departments in the university which are IT and Engineering. The university offer four degree programmes, two from IT and two from Engineering.
