Question
Consider a relation StudentInfo(StudNo, StudName, Major, Advisor, CourseNo, Ctitle, InstrucName, InstrucLocn, Grade). Assume it has the following functional dependencies: FD1: StudNo -> StudName FD2: CourseNo
Consider a relation StudentInfo(StudNo, StudName, Major, Advisor, CourseNo, Ctitle, InstrucName, InstrucLocn, Grade). Assume it has the following functional dependencies:
FD1: StudNo -> StudName
FD2: CourseNo -> Ctitle,InstrucName
FD3: InstrucName -> InstrucLocn
FD4: StudNo,CourseNo,Major -> Grade
FD5: StudNo,Major -> Advisor
FD6: Advisor -> Major
To make the StudentInfo table to be BCNF, the StudentInfo table has been decomposed into the following relations:
Student(StudNo, StudName)
StudMajor(StudNo, Major, Advisor)
StudCourse(StudNo, Major, CourseNo, Ctitle, Instrucname, InstrucLocn, Grade).
Does this decomposition satisfy BCNF? If not, apply further decomposition to make all relations satisfy BCNF
