Can someone define data aggregation and explain how it works? or What does it mean to define data agg

To define data aggregation, it’s the process of gathering and summarizing data from multiple sources. For example, a weather app pulls temps from thousands of stations but shows you one average.

It works by using queries (SQL) or tools like Excel PivotTables. Super useful for spotting patterns without drowning in details.

Why important? Businesses use it to track performance, like monthly sales reports.
