Have you ever need to create a 7-day trailing average in order to smooth out a graph? How about compare a value to the same value in the previous row?
Windowed aggregations are a powerful way to perform complex analysis, such as this, without leaving the comfort of the SQL. These functions operate on a defined group, or "window", of rows to return an aggregated value for each row. Window aggregations are supported for both uploaded tabular data, as well as live tables (where support exists in the connected database).
