[b]"Can someone define data aggregation and explain how it works?"[/b] or [b]"What does it mean to define data agg

To define data aggregation, think of it as compiling scattered info into a digestible format. For example, instead of listing every customer’s purchase, you’d show total revenue per region.

You can use Excel (pivot tables are your friend), Python (pandas library), or specialized tools like Looker.

It’s huge in analytics because raw data is noisy—aggregation cleans it up for decision-making.
