Normalization is the process of organizing data in a database so that it meets certain requirements. The three main objectives of normalization are to reduce data redundancy, to eliminate undesirable characteristics of data, and to improve the integrity of data. Normalization is usually done in three steps: first normal form (1NF), second normal form (2NF), and third normal form (3NF).
1NF, 2NF, and 3NF are normal forms that are used to normalize a database. 1NF is the most basic form of normalization and simply requires that all data be stored in a single table. 2NF requires that all data be stored in multiple tables, and that all data be linked together. 3NF requires that all data be stored in multiple tables, and that all data be linked together and that all data be related to each other.
1NF, 2NF, and 3NF are the three most commonly used normal forms in database design. They are often used in conjunction with each other to produce a well-designed database. 1NF is concerned with the organization of data within a database. It ensures that data is stored in a consistent and logical manner. 2NF is concerned with the relationships between data in a database. It ensures that data is related in a way that makes sense and that data is not duplicated. 3NF is concerned with the integrity of data in a database. It ensures that data is accurate and consistent. Normalization is an important part of database design. It ensures that databases are well-organized and that data is stored in a way that is both consistent and logical.
