What is normalization?

- Normalization is the way of organizing data in a database by removing redundancy and inconsistent dependency.

- Database normalization has the rules to be followed while creating databases.Each rule is called as normal form.

First Normal form states - Remove duplicate column and identify each set of related data with a primary key.

Second normal form - Create relationship between master and master detail tables using foreign key.

Third normal form - Remove the fields that do not depend on the primary key.

- It is the process of organizing data into related table.

- To normalize database, we divide database into tables and establish relationships between the tables.

- It reduces redundancy. It is done to improve performance of query.

What is normalization?

It is a step-by-step breakdown of data structure complexity into simple structure that facilitates no loss to information and relationship
