![Identify the key(s) and functional dependencies of the relation shown in R and then identify a
decomposition into Third normal form 3NF.
A university consists of several departments. Each department offers several courses in different
semesters. Students take admission in a department and enroll in a particular course taught by a
lecturer (any lecturer may take different courses in different semester) who is from the related
department and each lecturer tutors a group of students of his department. No student enrolls any
course outside of his department. Each lecturer is employed for a department. Any student may
retake any course to improve and all results(gpa) are recorded in R.
R relation keeps records about the results (gpa) in courses taken by students in different semesters
and also keeps record which lecturer taught that that course in that semester.
R (StudentID, Student_name, Student_email, Department_No, Dept_name, Dept_address,
Course_code, Course_title, Course_credit, GPA, Lecturer_ID, Lecturer_designation, Semester_id,
Semester_name, Semester_year)
