Window Functions

Window functions perform calculations across a set of rows that are related to the current row. Unlike standard aggregate functions that group rows into a single result row, window functions retain the individual rows and add a calculated value for each row based on the window frame. This allows you to perform analyses like calculating running totals, moving averages, or ranking within partitions of data without collapsing the rows.
