An Entity Relationship (ER) diagram is a graphical representation of entities and their relationships to each other, used in database design to illustrate the relationships between data objects. It is a visual representation of a database schema, showing the entities, attributes, and relationships between entities.ER diagrams are used to model the data requirements of an organization and can help identify relationships between entities, constraints, and business rules. They provide a clear picture of the data structures and the relationships between them, making it easier to understand the data requirements and to design a database that meets those requirements.
