Denormalization

A term from relational database theory.

Data is denormalized to improve the efficiency of queries/read operations against the data. Typically by reducing the number of joins that must be made when querying the data.

Denormalized data may be accessed via views on top of existing tables, or from a separate set of tables that contain a denormalized copy of the data from the tables that contain the normalized data.
