Database Normalization - how to do it and for what purpose?
Database normalization is a crucial process in database design aimed at reducing data redundancy and eliminating inefficiencies. As outlined in the article, normalization consists of several normal forms that assist in structuring data properly. The most commonly recognized normal forms are the first (1NF), second (2NF), and third normal form (3NF). Each of these forms has specific rules that help in minimizing data duplication. This approach is designed to make the database more consistent and efficient, which is particularly important in large systems. The examples and illustrations provided in the article ensure a better understanding of how to apply normalization practically, making it a valuable resource for database designers and programmers.
