what is normalization?
what is denormalization?

Answer Posted / koti

In relational database design, the process of organizing
data to minimize redundancy. Normalization usually involves
dividing a database into two or more tables and defining
relationships between the tables. The objective is to
isolate data so that additions, deletions, and modifications
of a field can be made in just one table and then propagated
through the rest of the database via the defined relationships.

De-normalization is introducing redundancy.
