What is Normalization?

Database normalization is a data design and organization method applied to data structures based on rules that help building relational databases. In relational database design, the method of organizing data to minimize redundancy is known as normalization. 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.
