14.28. Consider the relation R, which has attributes that hold schedules of courses and sections at a university; R = {Course_no, Sec_no, Offering_dept, Credit_hours, Course_level, Instructor_ssn, Semester, Year, Days_hours, Room_no, No_of_students}. Suppose that the following functional dependencies hold on R: {Course_no} β {Offering_dept, Credit_hours, Course_level} {Course_no, Sec_no, Semester, Year} β {Days_hours, Room_no, No_of_students, Instructor_ssn} {Room_no, Days_hours, Semester, Year} β {Instructor_ssn, Course_no, Sec_no} Try to determine which sets of attributes form keys of R. How would you normalize this relation?
