For more than 15 years, my colleagues and I at the Software Improvement Group (SIG) have been in the business of evaluating the quality of code, architecture, and development practices for our customers. Recently, we dove into our assessment data to discover—and quantify —trends in software development, each time comparing 2016 to 2017.

In Part 4 of the series, which focused on optimization of derived tables, I described a process of unnesting/substitution of table expressions. The TL;DR version of substitution/unnesting of CTEs is that the process is the same as it is with derived tables. You can find the script that creates and populates PerformanceV5 here.
