Database Normalisation Questions Medium
The purpose of the normalization rules in database design is to eliminate data redundancy and ensure data integrity. These rules help in organizing and structuring the database in a way that minimizes data duplication and inconsistencies. By following normalization rules, the database is divided into multiple tables, each serving a specific purpose and containing only relevant data. This helps in reducing data redundancy, improving data consistency, and facilitating efficient data retrieval and manipulation. Normalization also helps in maintaining data integrity by enforcing relationships between tables and preventing anomalies such as update, insert, and delete anomalies. Overall, the purpose of normalization rules is to optimize database design, improve data quality, and enhance the overall efficiency and effectiveness of the database system.
