Normalization means "The imposition of standards or
regulations". In the context of Relational Database Systems,
Database Normalization specifies a set of rules that splits
up a relational schema into a number of smaller subschemas,
in the objective of eliminating database anomalies. Database
normalization ensures that the data integrity and
consistency of the database is maintained. Each table in a
relational schema has a highest normal form indicating the
table's degree of vulnerability to logical inconsistencies
and anomalies. Database Normalization defines the steps to
decrease the degree of vulnerability in database systems.
Edgar F. Codd, the inventor of the relational model,
introduced the concept of normalization which is carried out
by the database designer of relational systems.
To determine and to achieve a highest normal form of
database systems please read
