Please provide Business rules, entities and ER diagram for the following Scenario:

Each of the students is enrolled in a single programme of study which involves a fixed core of courses specific to that programme as well as a number of electives taken from other programmes. Students work on courses and are awarded a grade in any course if he/she passes the course. Otherwise, the student has to re-take the failed course. The system needs to record the year and term in which the course was taken and the grade awarded to the student. Every student has a unique ID. The system also keeps the student name, birthday and the year he/she enrolled in the course.

The school employs lecturers to teach the students. A lecturer is allowed to work for one school only. Each lecturer is assigned an ID which is unique across the whole university. The system keeps the lecturers name, title, and the office room. A supervisor may be in charge of several lecturers, but a lecturer, however, reports to only one supervisor. A lecturer can teach many different courses. A course may also have been taught by many different lecturers.

The university is operated by committees. Each faculty has to have a number of committees with the same titles across the university, such as the Faculty Executive, the Post Graduate Studies Committee, the Health and Sanity Committee, and so on. The committees meet regularly, such as weekly or monthly. The frequency is determined by the faculty involved. A committees members are all lecturers. A lecturer may be a member of several committees.
