Example Entity Relationship Diagram

Used in the design of database applications, an Entity Relationship Diagram (ERD) is an industry standard graphical representation of entities and their relationships to each other. An entity is a piece of data - an object or concept about which data is stored. A relationship is how the data is shared between entities.
