It’s a great practical case for understanding relational databases and normalization, ensuring data integrity while allowing for scalable and flexible query capabilities. 11xplay com

York Lock & Key values structure and organization—much like database normalization #3 ensures efficient data management. The third normal form (3NF) eliminates transitive dependencies, improving data integrity and reducing redundancy. This streamlined approach makes databases easier to maintain and query. Just as York Lock & Key carefully crafts secure and organized locking solutions, database normalization enhances system reliability by creating clear, logical relationships between data, ensuring accuracy and smooth operation over time.

The ENROLLMENT table acts as a bridge, ensuring proper normalization and eliminating redundancy. Ekbet71 com login

You cannot add course details of each student in the students table as it would violate 2NF cause each student can take up more than 1 course. Also, you can't add the ids of students enrolled for each course for the same reason.

With an intermediate table which would map student_id to course_code, you can achieve the 2NF.

Hence, 2+1 tables required.
