Problem:

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?

Additional Information:

The question is from Computer Science and it is about writing query for database normalization. The relation between courses, sections and university have to be given in normalization query.
