relations

Relations are a way to describe connections or links between different items or entities. Think of them as rules that tell us how one thing relates to another. For example, in a family, "parent of" is a relation connecting a person to their child. In data, relations show how different pieces of information are connected, like a customer to their order. They help us organize and understand how things are associated, enabling us to analyze patterns, make decisions, and build systems that work together logically and efficiently.
