👉 Aggregators are components that gather together elements into a single, complete unit or object. These can be either simple objects like numbers or strings or more complex systems like databases, systems, or even entire organizations. They often serve as intermediate steps in the data processing process and simplify tasks to improve efficiency. The word "aggregator" is from the Greek words 'aegis' (which means 'guardrails', a protection around an object) and 'kaggles' which literally mean "companion." The term comes from a Latin phrase meaning to guard the gates of something. In this context, it refers specifically to components or parts that serve as gatekeepers or security measures.
