Answer / Deepak Maurya

Normalisation is a process used in database design to organize data in a logical and efficient manner. It aims to eliminate data redundancy, improve data integrity, and make the database easier to understand and manage. Normalisation has several stages (or 'normal forms'), each with its own set of rules for organizing data: first normal form (1NF), second normal form (2NF), third normal form (3NF), fourth normal form (4NF), and fifth normal form (5NF).
