"Normalization is a technique used by database administrators to reduce the redundancy of the data and eliminate any characteristics that impede the database's performance. Normalization is accomplished by separating the tables into individual smaller tables and using keys to relate the data. There are currently six levels of Normalization, including one through five normal forms and the Boyce-Codd Normal Form. There is a seventh (6NF) proposed. Each level uses a different set of rules to normalize the data."
