A University would like to create a database to record information about some of its activities. The university offers a number of degrees to students. A degree is described by a unique name, total number of credit points required to complete a degree, and several requirements that must be satisfied by the future students. The university offers three types of degrees: undergraduate degrees, postgraduate degrees, and graduate certificate. Postgraduate degrees are available only for the students who already got an undergraduate degree. A description of a postgraduate degree includes a list of acceptable undergraduate degrees. A description of a graduate certificate includes a requirement on the total number of years of professional experience.
Each degree consists of a collection of subjects. A description of a subject consists of its unique code, unique title, total number of credits points a subject is worth, and a list of subject learning objectives. The university employs academic staff members, tutors and support staff members. A description of a university employee consists of a unique employee number, first name last name and date of birth. First name, last name and date of birth uniquely identified each employee. Additionally, academic staff members and tutors are described by an academic degree achieved. Support staff members are described by a list of qualifications acquired in the past together with a date when each qualification has been acquired.
The university assigns the academic staff members and tutors to the subjects. A subject has one or two academic members assigned and a number of tutors. An academic staff member and tutor can be assigned to many subjects. Support staff members are assigned to the degrees. Each support staff member is assigned to one degree and a degree has one or more support staff members assigned.
The university is divided into faculties and faculties are divided into schools. Academic staff members and tutors belong to one school and each school consists of many academic staff members and tutors. The faculties and schools are described by the unique names.
