 All aggregate functions are deterministic, which means they always return the same value when they run on the same input values.

 ## Analytic functions
-Analytic functions compute an aggregate value based on a group of rows. However, unlike aggregate functions, analytic functions can return multiple rows for each group. You can use analytic functions to compute moving averages, running totals, percentages or top-N results within a group.

 ## Ranking functions
 Ranking functions return a ranking value for each row in a partition. Depending on the function that is used, some rows might receive the same value as other rows. Ranking functions are nondeterministic.
