The different entity relationship diagram is using the different symbols to represent the relationships between entities in a database for most information management projects.

Entity Relationship Diagram Tool

But ER diagrams often use boxes to represent entities. Diamonds are normally used to represent relationships and ovals are used to symbolize attributes. Entity Relationship Symbols Entities Symbol: Entity instance-person, place, object, event, concept Relationships Symbol: Chen ERD uses rectangles to represent entities, and diamonds to represent relationships appropriate for first-class objects. If an entity set participates in a relationship set, they are connected with a line. Attributes are drawn as ovals and are connected with a line to exactly one entity or relationship set.
