Entity Relationship Diagram (aka ERD, ER Diagram, E-R Diagram) is a well-tried software engineering tool for data modeling, system design and illustrating the logical structure of databases. Introduced by Peter Chen the ER modeling technique is now successfully used in software development, when creating conceptual data model of an information system.

There are used three basic elements for ERDs construction: entities, attributes, relationships. Chen's notation for ERD assumes the use of rectangles to represent entities and diamonds to represent relationships between first-class objects. Another popular notation for ER diagrams is Crow's foot notation.
