What is aggregation?

Aggregation is when you take many small things and put them together to make one bigger thing.

Imagine you have a bag full of marbles, tiny, round balls that are all different colors. Each marble by itself isn’t very special, but if you pour them all into a jar or shake them up in your hand, they become a group or a collection, and that’s aggregation!

Think of it like building with blocks. If you have one block, it's just a little square. But if you stack ten blocks on top of each other, you’ve made a tall tower, and that’s aggregation in action! You took many small parts (the blocks) to make something bigger (the tower).

You see aggregation all the time:

• When you add candies into a bowl for a party.
• When you put all your toys in one box.
• Even when you take all your socks out of the laundry and put them together.

Aggregation is just putting lots of little things together, like marbles, blocks, or socks, to make something bigger and more fun!
