Database Normalization 1NF, 2NF, 3NF with Examples

Database normalization is the process of organizing data in a database to minimize redundancy, reduce data inconsistencies, and ensure data integrity.

In this tutorial, you will learn about 1NF, 2NF, and 3NF with examples.
1NF (First Normal Form): Explore the requirements and principles of 1NF, the initial step in normalization, with real-world examples to illustrate the concept.

2NF (Second Normal Form): Delve into the complexities of 2NF, understanding how it builds upon 1NF to further eliminate data redundancies and inconsistencies.

3NF (Third Normal Form): Uncover the advanced principles of 3NF, focusing on achieving a higher level of data integrity and a more streamlined database structure.
