A. Consider the following relation R with all functional dependences F and normalize it into 2NF, 3NF, and BCNF. R={Patient_No,Patient_Name,App_No,Time,Doctor} F= { Patient_No --> Patient_Name Patient_No, App_No --> Time, Doctor Time --> App_No } B. Explain why the following relation R is in 3NF but not in BCNF. R={a,b,c,d} F= {a,b --> c,d a,d --> b}
