15.5 Summary
In this chapter we explored an in-depth definition and example for the use of denormal-

increase efficiency for query processing.
15.6 Literature Summary
The idea for extending a table for usage efficiency came from Schkolnick and Sorenson
[1980], and practical advice on denormalization is given in Rodgers [1989].
