Consider the relation R, which has attributes that hold schedules of courses and sections at a
university;
R = {CourseNo, SecNo, OfferingDept, CreditHours, CourseLevel, InstructorSSN, Semester, Year,
Days_Hours, RoomNo, NoOfStudents}.
Suppose that the following functional dependencies FDs hold on R:
{CourseNo} → {OfferingDept, CreditHours, CourseLevel}
{CourseNo, SecNo, Semester, Year} → {Days_Hours, RoomNo, NoOfStudents, InstructorSSN}
{RoomNo, Days_Hours, Semester, Year} → {InstructorSSN, CourseNo, SecNo}
Try to determine which sets of attributes form keys of R. How would you normalize this relation?
