Challenging. I didn't pick up on what to do to change the queries to get them to run/// and had to use the suggested/proposed solutions. More practice needed, I guess.

Best lab I've taken by far. Hands on, and meaningful questions that helped me to better understand the concepts. One question I was left with concerning the topics in this lab: I still don't understand the functionality of the UNNEST() function, as the queries still run with the correct results when using just the cross join by itself. What does the UNNEST function add to the query?
