entity-relationship diagram, ER-diagram, database ERD
An Entity-Relationship Diagram (ERD) is a visual presentation of entities and relationships. That type of diagrams is often used in the semi-structured or unstructured data in databases and information systems. At first glance ERD is similar to a flowch

Entity Relationship Diagram Examples

Create an Entity-Relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements. By nature it is an abstract visualization, the first step in the design process towards creating a logical and functional database.

ConceptDraw DIAGRAM diagramming and vector drawing software gives the ability to describe a database using the Entity-Relationship model. Entity-Relationship Diagram(ERD) solution from the Software Development area supplies the ConceptDraw DIAGRAM with icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.

Entity-Relationship Diagram (ERD) with ConceptDraw DIAGRAM

Entity-Relationship Diagram (ERD) serves for detailed description of structures and databases. An ERD represents a diagram made up mainly of rectangular blocks (for entities, or data) linked with relationships. The links between the blocks describe relations between these entities. There are three types of relationships: one-to-one,
one-to-many, many-to-many.
