What is Normalization ?

Normalization is a process for assigning attributes to entities. It reduces data redundancies and helps eliminate the data anomalies.

Normalization works through a series of stages called normal forms:

First normal form (1NF)

Second normal form (2NF)

Third normal form (3NF)

Boyce-Codd Normal Form (BCNF)

The highest level of normalization is not always desirable.
