Database normalization is the process of structuring a relational
database[clarification needed] in accordance with a series of so-called
normal forms in order to reduce data redundancy and improve data
integrity.
Normalization entails organizing the columns (attributes) and tables
(relations) of a database to ensure that their dependencies are
properly enforced by database integrity constraints. It is accomplished
by applying some formal rules either by a process of synthesis
(creating a new database design) or decomposition (improving an
existing database design).
Normalization is a technique for producing a set of suitable relations
that support the data requirements of an enterprise.
