It was great to see how to perform queries on structs and arrays with BigQuery

Great session - I know only traditional SQL, so learning about STRUCT and ARRAY constructs is not only very informative, but it helps me think in a different conceptual way when working with denormalized data sets. One question I had is in Lab Question: Unpacking ARRAYs with UNNEST( ). I was able to produce the same answers using just the CROSS JOINs with no UNNESTing. So I'm a bit unclear why you would need the UNNEST function when just CROSS JOIN seemed to be sufficient.

The time is a bit limited compared with the previous lab. I think 15 min. more to understand how the syntax is built would be useful
