Aggregation is a fancy way of saying that you're treating a bunch of related objects as a single unit, like an order and its line items. It's a key concept in Domain-Driven Design (DDD) that helps keep your code organized and manageable, even if it sounds like something straight out of a business school textbook.

How to use it in a sentence

• "I'm not sure why the aggregation is failing, but I bet it's because some genius decided to use a NoSQL database for this project."

• "If we don't get this aggregation logic sorted out soon, I'm going to have to cancel my plans to binge-watch the latest season of Silicon Valley this weekend."
