Stop Coding and Start WritingPart I explained the importance of SQL and built a solid foundation for SQL development. Part II discussed sets and advanced features needed to build powerful SQL statements. We now have the motivation, efficient processes, and advanced knowledge, but that is not enough. Part III discusses the styles and patterns needed to write elegant SQL.
