Introduction
Normalization: The practice of normalization improves the integrity of data in the table by removing redundant data and duplication. Additionally, normalization aids in database data organization. Setting the data onto the tabular form and removing duplicate data from relational tables involves several steps.
In order to make sure that restrictions on database integrity effectively carry out their obligations, normalization arranges the columns & tables of a database. It is a methodical method of breaking down tables to get rid of redundant data and undesired traits including Insertion, Update, & Deletion anomalies.
