Denormalization can be a controversial topic among database designers. Some believe that any database should be fully normalized (even using all the normal forms discussed in Appendix B, available on the book’s Web site). Others look for ways to denormalize to improve processing performance. Contact a database designer or administrator in an organization with which you are familiar. Ask whether he or she believes in fully normalized or denormalized physical databases. Ask the person why he or she has this opinion.
