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