Third Normal Form – Non-key attributes must only be dependent on candidate keys.Second Normal Form – Every non-key property must be dependent on the entirety of every candidate key, not simply a portion of a key.First Normal Form – Avoids repeated groups by placing them on their table and connecting them with a one-to-many relationship.It becomes difficult to manage and update the database without data loss if it is not normalized. It is a method of deconstructing tables used to minimize data redundancy (repetition) and undesired characteristics such as Insertion, Update, and Deletion anomalies. Normalization organizes a database’s columns and tables to guarantee that database integrity constraints execute their dependencies correctly.

It is a multi-step procedure that converts data into a tabular format and removes duplicate data from relational tables. Normalization also aids in the organization of data in a database.
