What tasks do normal forms help solve in the normalization process of a database?

Normal forms in the process of database normalization help solve the following tasks:

• Eliminating data redundancy, which reduces the volume of stored information and decreases the likelihood of errors during updates.
• Preventing anomalies during insertion, updating, and deletion of data.
• Ensuring data integrity and the logical structure of the database.
• Dividing data into logically related tables, which simplifies maintenance and expansion of the database.

For example, the first normal form (1NF) requires all fields to be atomic, the second (2NF) eliminates partial dependencies, and the third (3NF) addresses transitive dependencies.
