Question

. Consider the relation R, which has attributes that hold schedules of course
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:
irses
{Course_no) → {Offering_dept, Credit_hours, Course_level}
{Course_no, Sec_no, Semester, Year} → {Days_hours, Room_no,
No_of_students, Instructor_ssn}
{Room_no, Days_hours, Semester, Year} → {Instructor_ssn, Course_no,
Sec_no}
Try to determine which sets of attributes form keys of R. How would you
normalize this relation?
