Normalization is a design technique that is widely used as a guide in designing relational databases. Normalization is essentially a two steps process that puts data into tabular form by removing repeating groups and then removes duplicate data from the relation tables.
I have made some guidelines for ensuring that our database is being normalized. There are referred to as normal forms and numbered from one (the lowest form of normalization, referred to as first normal form (1NF)).
In practical applications, you will often see 1NF, 2NF and 3NF.
First normal form (1NF) is considered to be part of the formal definition of a relation, the basic relational model: historically it was defined to disallow multivolume attributes, composite attributes and their combinations.
The relational table, by definition, is in first normal form. All values of the columns are atomic, so they contain not repeating values.
Second Normal Form
A second normal form (2NF) is based on the concept of full functional dependency.
In order to be in second normal form, a relation must first fulfill the requirements to be in 1NF additionally, each no key attribute in the relation must be functionally dependent upon the primary key.
Third Normal Form
In order to be in third normal form (3NF), a relation must first fulfill the requirements to be in second normal form (2NF). Additionally, all attributes that are not dependent upon the primary key must be eliminated. Fantastic Web Design
