Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.
Normalization is used to eliminate data redundancy by breaking up tables into smaller tables and defining relationships between them.
It helps in reducing data anomalies such as insertion, update, and deletion anomalies.
Normalization is achieved through a series of normal forms (1NF, 2NF, 3NF, BCNF, etc.)
