What is the purpose of the 'Totals' row in Access queries?

The 'Totals' row in Access queries is designed to perform aggregate calculations on grouped data. When this feature is enabled, it allows users to summarize data by applying functions such as Sum, Count, Average, Min, Max, and more. These calculations are typically applied to a specific field within a grouped dataset, enabling users to analyze data efficiently and gain insights from bulk records.

For example, when creating a query that groups sales data by product categories, the 'Totals' row lets users determine the total sales for each category by utilizing the Sum function. This makes it significantly easier to interpret large datasets and derive meaningful conclusions from them, as compared to reviewing individual records without any calculations. The focus on aggregate calculations distinguishes the 'Totals' row from other functionalities in Access, such as sorting or filtering data, which serve different purposes in data management and analysis.
