What are the advantages of applying the third normal form in database design?

The Third Normal Form (3NF) helps eliminate data redundancy and update anomalies in a database. Applying 3NF ensures:

• Removal of transitive dependencies, reducing data duplication.
• Increased data integrity, as each table is responsible for one entity.
• Simplification of database maintenance and scaling.
• Improved query performance by reducing the amount of stored data.

For example, if employee information includes department details, changing the department name would require updating all records. In 3NF, the department is separated into a different table, preventing such issues.
