   Windows Functions in SQL Server

   Windows functions in SQL Server are a powerful set of functions that operate across a specific "window" of rows defined by the OVER() clause. These functions allow for computations and aggregations over this defined window, enabling analytical and statistical calculations without altering the overall result set. Commonly used functions include ROW_NUMBER(), RANK(), DENSE_RANK(), SUM(), AVG(), and COUNT(). These functions greatly enhance query capabilities, aiding in tasks such as ranking data, calculating running totals, and performing comparative analyses within specified partitions or orderings. They play a vital role in advanced SQL operations and reporting.
