What entities are involved in the ER diagram?

An ER diagram, short for Entity-Relationship diagram, represents the various entities involved in a system or database. Entities are objects or concepts that exist in the real world and have distinct characteristics and relationships with other entities. In an ER diagram, entities are represented by rectangles and they serve as the building blocks of the diagram. These entities can include anything from people, places, and things to abstract concepts or events. Each entity has its own set of attributes that describe its properties or characteristics. Additionally, entities can have relationships with other entities, which are represented by lines connecting them. Overall, entities are fundamental components of an ER diagram, representing the various objects and concepts that exist within a system or database.
