Summary

We began this chapter with a discussion of the Performance Recording dashboard. This was important because many of the subsequent exercises utilized the Performance Recording dashboard to examine underlying queries.

Then we covered working with data sources, including joining, blending, and efficiently working with Data Sources. This was followed by a discussion on generating and using extracts as efficiently as possible. By focusing on data sources for these three sections, we learned best practices and what to avoid when working with either remote datasets or extracts.
