Yo, data aggregation is like turning a messy pile of Legos into a neat set. You take all those tiny pieces (data points) and build something bigger and clearer (summary stats).
How it works? Tools like Google Analytics or SQL do the heavy lifting. You tell them how to group stuff (by day, user, etc.), and they crunch the numbers.
Real-world example: Netflix uses it to see what shows are trending instead of tracking every single view.
