Views: Group-By and Aggregate
Views can be used to expose the results of a custom query as a virtual table.
Sometimes we might want to fetch some data derived by aggregating (avg, min, max, etc.) over a group of rows in a table.
This view will fetch the average article rating for each author across two tables.
