What is Normalization?
- Normalization is a process in relational database management systems (RDBMS) that involves organizing tables and data to reduce redundancy and dependency.
- The goal of normalization is to minimize data anomalies and improve data integrity by ensuring that data is stored in a structured and efficient manner.
- The process was introduced by Edgar F. Codd, a pioneer in the field of relational databases.
- The normalization process is typically divided into several normal forms, each representing a level of normalization. The most common normal forms are First Normal Form (1NF), Second Normal Form (2NF), Third Normal Form (3NF), Boyce-Codd Normal Form (BCNF), and Fourth Normal Form (4NF).
- Each successive normal form builds upon the requirements of the previous one.
