Abstract
Indexes are a crucial aspect of your application design. Correct implementation requires an in-depth knowledge of the data, how it is distributed, and how it will be used. Too often, indexes are treated as an afterthought in application development, and performance suffers as a consequence.
This chapter examines in detail the different types of indexes, including B*Tree, bitmap, function-based, and application domain indexes, and discusses where they should and should not be used. I’ll also answer some common queries in the “Frequently Asked Questions and Myths About Indexes” section, such as “Do indexes work on views?” and “Why isn’t my index getting used?”
