What is Normalization in a Database?
Normalization is used to minimize redundancy and dependency by organizing fields and table of a database.
There are some rules of database normalization which commonly known as Normal From and they are:
- First normal form(1NF)
- Second normal form(2NF)
- Third normal form(3NF)
- Boyce-Codd normal form(BCNF)
Using these steps, the redundancy, anomalies, inconsistency of the data in the database can be removed.
