Summary

This chapter covered different ways to break queries into smaller functional parts and the advantages and disadvantages of each approach. It covered the potential pitfalls of one often-used optimization tool—temporary tables—and showed how common table expressions can be used as an alternative that doesn’t stymie the query optimizer. It also discussed views and materialized views and their impact on performance. Finally, it briefly addressed partitioning and parallel execution.
