What is entities meaning?

Entities refers to any distinct and unique object or thing that can be identified and distinguished from other similar objects or things. An entity can be a physical object such as a person, animal, or machine, or it can be an abstract concept such as a company, organization, or a relationship. Entities are often used in databases, where they can be defined as tables, columns, or fields, and used to organize and store data. Entities are also used in computer programming and artificial intelligence, where they can represent objects or concepts in a particular domain. In general, entities are used to describe the properties, attributes, and relationships of objects, and they can be grouped together to form complex systems or networks.
