Relationship with attributes StudentId, StudentName, GroupId, GroupName, CourseId, CourseName, LecturerId, LecturerName, Mark

  1. Incrementally bring this relationship to the fifth normal form.

    1. (StudentId, StudentName, GroupId, GroupName, CourseId, CourseName, LecturerId, LecturerName, Mark) => (StudentId, StudentName, GroupId, GroupName, CourseId, CourseName, LecturerId, LecturerName, Mark)

    2. (StudentId, StudentName, GroupId, GroupName, CourseId, CourseName, LecturerId, LecturerName, Mark) => (StudentId, StudentName, GroupId, GroupName) ; (GroupId, GroupName) ; (CourseId, CourseName) ; (LecturerId, LecturerName) ; (GroupId, CourseId, LecturerId, LecturerName) ; (StudentId, CourseId, Mark)

    3.  (StudentId, StudentName, GroupId, GroupName) => (StudentId, StudentName, GroupId, GroupName)
 (GroupId, GroupName) => (GroupId, GroupName)
 (CourseId, CourseName) => (CourseId, CourseName)
 (LecturerId, LecturerName) => (LecturerId, LecturerName)
 (GroupId, CourseId, LecturerId, LecturerName) => (GroupId, CourseId, LecturerId, LecturerName)
 (StudentId, CourseId, Mark) => (StudentId, CourseId, Mark)

    4.  (StudentId, StudentName, GroupId, GroupName) => (StudentId, StudentName, GroupId, GroupName)
 (GroupId, GroupName) => (GroupId, GroupName)
 (CourseId, CourseName) => (CourseId, CourseName)
 (LecturerId, LecturerName) => (LecturerId, LecturerName)
 (GroupId, CourseId, LecturerId, LecturerName) => (GroupId, CourseId, LecturerId, LecturerName)
 (StudentId, CourseId, Mark) => (StudentId, CourseId, Mark)

    5.  (GroupId, GroupName) => (GroupId, GroupName)
 (CourseId, CourseName) => (CourseId, CourseName)
 (LecturerId, LecturerName) => (LecturerId, LecturerName)
 (StudentId, CourseId, Mark) => (StudentId, CourseId, Mark)
 (GroupId, CourseId, LecturerId, LecturerName) => (GroupId, CourseId, LecturerId, LecturerName)
 (StudentId, StudentName, GroupId, GroupName) => (StudentId, StudentName) ; (StudentId, GroupId, GroupName)

    6.  (GroupId, GroupName) => (GroupId, GroupName)
 (CourseId, CourseName) => (CourseId, CourseName)
 (LecturerId, LecturerName) => (LecturerId, LecturerName)
 (StudentId, StudentName) => (StudentId, StudentName)
 (StudentId, CourseId, Mark) => (StudentId, CourseId, Mark)
 (StudentId, GroupId, GroupName) => (StudentId, GroupId) ; (GroupId, GroupName)
 (GroupId, CourseId, LecturerId, LecturerName) => (GroupId, CourseId, LecturerId) ; (LecturerId, LecturerName)
