What is Entity?

In computer science, an entity is an abstract idea or concept that represents a distinguishable thing. This can be a real-world object, a concept, or a piece of information. The specific meaning of 'entity' depends heavily on the context in which it's used. In database modeling, entities are often used to represent real-world objects, such as customers or products, about which data is stored. In object-oriented programming, it might refer to an object. In natural language processing, entities are often named entities, such as people, organizations, or locations, identified in text. The common thread is that an entity represents a discrete, identifiable thing within a system or domain.
