Consider the following case:

A) A university keeps track of each students name, students number, social security number, current address and phone, permanent address and phone, birth date, sex, major department, minor department (if any), and degree program (B.A, B.S, M.S, M.A, PhD). We need to refer to the City, Emirate, PO Box of the students permanent address and to the students last name. Both social security number and students number have unique values for each student.

B) Each department is described by a name, department code, office number, office phone, and college. Both name and code have unique values for each department.

C) Each course has a unique course name, description, course number, credit hours, level, and offering department. The value of course number is unique for each course.

D) Each section has an instructor, semester, year, course, and section number. The section number distinguishes sections of the same course that are taught during the same semester/year; its values are 1,2,3, up to the number of sections taught during each semester. E) A grade report has a student, section, letter grade, and numeric grade (0, 1, 2, 3, and 4).
