The basic Chen diagram was developed by Dr. Peter Chen in 1976. The Chen Entity-Relationship Diagram or Chen ERD notation model is a popular standard and is widely used in software design. A Chen ERD is useful for modeling the basics of entities and relationships because it presents an abstract view of the associations. An ERD contains symbols and connectors to visualize the major entities. As Chen ERD illustrates, entities are represented by rectangles, attributes are circular callouts to the entities, and relationships connect the entities with a diamond shape. Instead of creating Chen Entity-Relationship diagrams from scratch, try EdrawMax’s ready-to-use templates or use them as inspiration for your own design.
