A process to validate and improve logical design so that it
satisfies certain constraints that avoid unnecessary
duplication of the data.
Normalization is a formal technique for analyzing a relation
based on its primary key and the FDs between the attributes
of that relation.
The normalization process was first proposed by Codd 1972.
