Understanding Denormalization. Denormalization is the process of reversing the transformations made during normalization for performance reasons. It’s a topic that stirs controversy among database experts; there are those who claim the cost is too high and never denormalize, and there are those that tout its benefits and routinely denormalize.

One aspect is nullability. Say there is a normalized table with a not null column. That table is the right side in an outer join where there are non-matching rows. Now the denormalized result must show null for that not-null column in some rows. Declared uniqueness may be affected. A normalized table could have a unique constraint.

Denormalization is the deliberate bringing of a database structure to a state that doesn’t meet the requirements of normalization. Denormalization is used to add redundancy to fulfill a query quickly. In this case, the number of tables decreases, in contrast to normalization. Fewer connections reduce errors.
