Answers
Normalization is a technique of designing databases to reduce the duplication of data. It is achieved by linking table through joins. The linked field(s) are called keys. Normalization can be done to 5 stages, however practically it is only done till the third normal form of 3NF.
1NF : Repeating groups are removed
2NF: Functional dependency is removed
3NF: Transitive dependency is removed
4NF: Multi-value dependency is removed.
