Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.

• Normalization is divided into different normal forms such as 1NF, 2NF, 3NF, BCNF, and 4NF.

• Each normal form has specific rules to eliminate redundancy and dependency issues.

• For example, 1NF ensures that each column contains atomic values, 2NF eliminates partial dependencies, and 3NF removes transitive dependencies.
