Chen ERD

This Chen ERD is thought to be a more straightforward way of depicting entities and their relationships. It is widely used in database design and software development. Chen's entity-relationship diagram (ERD) notation reveals the information in the data and domain models through entities, attributes, and relationships. Chen ERD is easily explained by citing an example of a banking system, where, unlike other ER diagram notations, the details can be learned more about as standalone boxes. A Chen ERD notation model is widely used worldwide to understand more about database and software design. The ER model is built on a realistic view of how the real world is made up of entities and the relationships between these entities.
