QUESTION 3

  1. How do we know the following relation with the following dependencies is BCNF?

     

    course ( course_id , title , dept_name , credits )

     

    Functional Dependencies

    course_id → title , dept_name , credits
    building , room_number → capacity
    course_id , sec_id , semester , year → building , room_number , time_slot_id

     

       

    course_id, dept_name is a superkey

       

    course_id is a candidate key

       

    dept_name is a superkey

       

    course_id is a superkey
