What advantages does the application of normal forms provide in database design?

Applying normal forms in database design provides the following advantages:

• Elimination of data redundancy. This reduces the amount of stored information and decreases the likelihood of errors during updates.
• Improvement of data integrity. Normalization helps avoid insertion, update, and deletion anomalies.
• Simplification of maintenance and scaling. A clear table structure makes understanding and modifying the database easier.
• Query optimization. Properly normalized tables allow for more efficient queries and updates.

For example, separating information about customers and orders into different tables using keys helps avoid duplicating customer data in each order record.
