What is Database Normalization?
Database normalization is the process of removing redundant data from your tables in to improve storage efficiency, data integrity, and scalability.
In the relational model, methods exist for quantifying how efficient a database is. These classifications are called normal forms (or NF), and there are algorithms for converting a given database between them.
Normalization generally involves splitting existing tables into multiple ones, which must be re-joined or linked each time a query is issued.
Edgar F. Codd originally established three normal forms: 1NF, 2NF and 3NF. There are now others that are generally accepted, but 3NF is widely considered to be sufficient for most applications. Most tables when reaching 3NF are also in BCNF (Boyce-Codd Normal Form).
