relationships between those tables according to rules
designed both to protect the data and to make the database
more flexible by eliminating two factors: redundancy and

data to minimize redundancy. Normalization usually involves
dividing a database into two or more tables and defining
relationships between 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
through the rest of the database via the defined relationships.

Normalization is the process of decomposition of complex
data in to simple way.
Denormalization is basically applied in the case the
database is over-normalised and no. of joins required to
fetch the data are too much. It is a purposeful redundancy
of some of the data to avoid the overhead of joins.
