  6. Normalization of Multiple Reports • STUDENT REPORT: • UNF: • STUDENT (stu#, stu_name, stu_address, stu_crse, stu_mode, lect#, lect_name, {subject#, subject_name, yr_sem, grade}) • 1NF: • STUDENT (stu#, stu_name, stu_address, stu_crse, stu_mode, lect#, lect_name) • AC-REC (stu#, subject#, subject_name, yr_sem, grade) • 2NF: • STUDENT (stu#, stu_name, stu_address, stu_crse, stu_mode, lect#, lect_name) • AC-REC (stu#, subject#, yr_sem, grade) • SUBJECT (subject#, subject_name) • 3NF, BCNF: • STUDENT (stu#, stu_name, stu_address, stu_crse, stu_mode, lect#) • LECTURER (lect#, lect_name) • AC-REC (stu#, subject#, yr_sem, grade) • SUBJECT (subject#, subject_name)
