What is Normalization?
Normalization is the process of organizing the data to reduce duplicates in tables. It improves data integrity step by step.
Large tables are broken down into small tables and for every interaction to occur on the data, data present in the database has to be normalized.
Normal Forms
The following are the four normal forms used to enhance the distribution of data.
1st Normal Form (1NF)
2nd Normal Form (2NF)
3rd Normal Form (3NF)
Boyce-Codd Normal Form(BCNF)
