Data normalization is the process of organizing data in a database to reduce redundancy and improve integrity. It is a database design method that involves dividing information into smaller, consistent, and related parts, which eliminates unnecessary data duplication. Normalization helps to eliminate the risk of data errors and facilitates effective data management. As a result, databases become more efficient, easier to maintain, and more resilient to anomalies. Data normalization is a key activity in database design, especially in systems that store large amounts of information.
