Entity Relationship Software

Entity Relationship Diagram (ERD) is a leading data modeling tool that is used to illustrate the logical structure of database, helps to organize and represent your project's data in terms of entities, attributes and relationships. To describe the database structure usually is used the ERD Chen's or Crow's Foot notation. Chen's notation supposes the representation of entities by rectangles with the entities names inside, relationships by diamonds and attributes by ovals connected with a line to exactly one entity. In Crow's Foot notation the boxes are used to depict the entities and their attributes, the lines between them - to depict relationships. ConceptDraw DIAGRAM software extended with Entity-Relationship Diagram (ERD) Solution is convenient and useful for designing the ER Diagrams, and supports the use of Chen's or Crow’s Foot notation according to your needs and desires. The ERD diagrams produced with ConceptDraw DIAGRAM Entity Relationship Diagram software can be successfully used in whitepapers, presentations, posters, datasheets, technical materials, etc.
