Data Normalization

Data normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It involves breaking down a table into smaller tables and defining relationships between them. The main goal of data normalization is to minimize data redundancy, which means that each piece of data is stored in only one place. This helps to prevent inconsistencies and anomalies in the data, and makes it easier to update and maintain the database. There are several levels of data normalization, known as normal forms, with each level building on the previous one. The most commonly used normal forms are first normal form (1NF), second normal form (2NF), and third normal form (3NF).
