What article on segment.com/docs is affected?

https://segment.com/docs/connections/storage/warehouses/schema/

What part(s) of the article would you like to see updated?

It is unclear how to correlate tables, for instance, how to determine what the activegroup or activescreen is at the time of atracks event. It is also unclear what exactly theanonymous_id is.
More exacting correlations for each data point with other tables and the Segment API would be much appreciated to take out the guess-work.
