 Normalization in short :

1NF : Ensure atomic(not a collection of) values in a column,
Ensure values of same data-type in a column

2NF : Remove partial dependencies : i.e. a column not depending on all the columns forming the primary key, but on some of them.

3NF: Remove transitive dependencies, i.e. a column not depending directly on the the primary key,, but on another column that depends on the primary key.
