Data aggregation = taking big, messy data and making it small and useful.
Example: Your phone tracks steps daily. Weekly steps? That’s aggregated data.
It’s a big deal because it saves time and helps make decisions faster.
Not the same as analysis—analysis asks "why?" aggregation just sums things up.
Look into SQL for heavy-duty aggregation.
