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

Data aggregation is like making a smoothie—you blend a bunch of ingredients (data) into something easier to consume (summary).

How? Tools like Tableau, SQL, or even Google Data Studio. You pick what to group (dates, categories) and how to measure (sum, count).

Example: Uber aggregates rides to see peak hours. Handy, right?
