Description: Entities are objects or components that can be identified and manipulated within a system. In the context of databases and programming, an entity represents a unit of data that has an independent existence and can be described by its attributes. For example, in a data management system, an entity could be a ‘Customer’, which would have attributes such as name, address, and phone number. Entities are fundamental for the organization and structuring of data, allowing developers and analysts to model the real world in computer systems. In database management systems, entities are used to define tables, where each row represents an instance of the entity and each column represents an attribute. This structure facilitates the querying, updating, and management of data efficiently. Additionally, entities can relate to each other, forming a more complex data model that reflects the interactions and dependencies of the real world. In summary, entities are key components in data architecture, providing a framework for the organization and manipulation of information in various technological applications.
