This Chen ER Diagram for Admin and User depicts the data model of an information system's admin and user. An admin and user entity-relationship diagram (Chen notation). It shows the entities as well as their characteristics. Because it presents an abstract view of the associations, Chen's database notation is useful for modeling the fundamentals of entities and relationships. These diagrams are a good place to start when learning about database structure, especially for simple databases or examples. This notation is also useful for quick diagramming and brainstorming. Rectangles are used to represent entities. Attributes are circular references to entities. With a diamond shape and descriptive text, relationships connect the entities.
