Suppose a single relation (table) is used to record the information about students’ enrollment in courses. We assume that each student may enroll in more than one course and one course is assigned to one instructor. All questions below are based on the following ENROLLMENT unnormalized table. ENROLLMENT StudentID StuName CourseCode CourseName Grade CreditHr Instructor InstrOffice 1021234 Ali 1102 1201 Database Internet A B 3 3 Zaid Sumaiya 5.01 5.05 1024131 Amina 1201 1401 Internet Operating System C B 3 3 Sumaiya Abdullah 5.05 5.10 1. What would be the First Normal Form (1NF) relation? Identify the primary key. 2. Identify the functional dependencies represented by the attributes shown in the ENROLLMENT table. Label partial or transitive dependency where applicable.
