Database normalization helps us remove data redundancies and repetitions. It not only helps us save space (these days we don’t have much problem with space) it also helps us organize the data so that it can be conveniently retrieved as and when needed. There are four kinds of normal forms, viz, the first normal form, the second normal form, the third normal form and the Boyce Code normal form.
The process of normalization begins with the first normal form. The entire process is explained in this article.
