Each department runs a number of courses. The university provides a set of modules used in different courses. Each course uses a number of modules but not every module is used. A course is assigned a unique course code and a module is identified by a unique module code. A module can be used in one course only, but can be studied by many students. In addition to the module code each module unique title, start date, end date, texts (books), and assessment scheme (i.e., coursework and exam marks percentages) are also stored.
Each course is managed by a member of academic staff, and each module is coordinated by a member of academic staff also. The database should also store each course unique title, and duration (in years).
A student can enroll in one course at a time. Once enrolled a student is assigned a unique matriculation number. To complete a course, each student must undertake and pass all the required modules in his/her course. This requires that the database store the…
