In relational database design, the process of organizing data to minimize redundancy is called normalization.Normalization is obtained via splitting up data in to separate tables and setting up relations between these tables

the main objective of doing this is to insert , delete and update data portions isolated and hassle free, and this change is propagated through out the database with relationships

 

De normalization is the switching up from higher to lower normal forms in order to speed up the database regardless of normalization, this also play a significant roll in DB administration
