Database Normalization
Understanding the Basics and Advanced Levels of Database Normalization If you’re new to database design, you’ve probably heard about database normalization. This is the process of organizing data in a database so that it is consistent, efficient, and easy to manage. There are several levels of normalization, each with their own benefits and use cases. In this article, we’ll cover the basics of normalization, including first normal form (1NF), second normal form (2NF), third normal form (3NF), and other advanced normal forms.
