What is Normalization?
Database normalization is a data design and organization method applied to data structures based on rules that help building relational databases.

Normalization usually includes dividing a database into two or more tables and defining relationships among the tables. The objective is to isolate data so that additions, deletions, and modifications of a field can be made in just one table and then propagated by the rest of the database via the explained relationships.
