Second Normal Form(2nd) (Eliminating Redundant Data)

A relation is in second normal form if it is in 1NF and every non key attribute is fully functionally dependent on the primary key.

It is in first normal form
All non-key attributes are fully functional dependent on the primary key

The First Normal form deals with the atomicity whereas the Second Normal Form deals with the relationship between the composite key columns and non-key columns.

To achieve the next progressive level your table should satisfy the requirement of First Normal Form then move towards the Second Normal Form.

 Let see the example from above 1st Normal From

Pen Red 3.0 0.40
Pen Blue 3.0 0.40
Scale Red 3.0 0.40
Scale Yellow 3.0 0.40
Bag Blue 120.0 12.52
Bag Black 120.0 12.52

Table is not in Second Normal Form because the price and tax depends on the item, but not color.

What is Normalization? 

What is Normalization? 

Normalization is a database design technique which organizes tables in a manner that reduces redundancy and dependency of data.

It divides larger tables to smaller tables and link them using relationships.

In this tutorial, you will learn-

The inventor of the relational model Edgar Codd proposed the theory of normalization with the introduction of First Normal Form and he continued to extend theory with Second and Third Normal Form. Later he joined with Raymond F. Boyce  to develop the theory of Boyce-Codd Normal Form.

Theory of Data Normalization in Sql is still being developed further. For example there are discussions even on 6th Normal Form. But in most practical applications normalization achieves its best in 3rd Normal Form. The evolution of Normalization theories is illustrated below

1st Normal Form >> 2nd Normal Form >> 3rd Normal Form >>4th Normal Form >>  5th Normal Form >>6th Normal Form

Database Normalization Examples –

Assume a video library maintains a database of movies rented out. Without any normalization all information is stored in one table as shown below.

Further We shall discuss on different normal forms in detailed:
