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