Consider the relation schemas Student(StudentlD, Name, DoB, Email) where StudenlD is its primary key, and Enrol(StudentlD, CourseNo, Semester, Status, EnrolDate) where (StudentID, CourseNo, Semester) is its primary key. The foreign key StudentID in Enrol references StudentID in Student. The true/false question: the StudentID values in Enrol must be distinct. Select one: O True O False In SQL, INDEX is used to enforce referential integrity between two tables. Select one: O True O False
