Entity Relationship Diagram - ERD - Software for Design Crows Foot ER Diagrams

ER-model is a data model which lets describe the conceptual schemes in a specific subject area. It can help to highlight the key entities and specify relationships that can be established between these entities. During the database design, it is realized the transformation of ER model into certain database scheme based on the chosen data model (relational, object, network, etc.). There are used two notations for ERDs: Crow's Foot and Chen's. Crow's Foot notation proposed by Gordon Everest represents the entity by rectangle containing its name (name must be unique within this model), and relation - by the line which links two entities involved in relationship. The relationship's plurality is graphically indicated by a "plug" on the end of the link, the optionality - by a circle. Entity-Relationship Diagrams based on Crow's Foot notation can be easily drawn using the ConceptDraw DIAGRAM. Extended with Entity-Relationship Diagram (ERD) solution, it is the best ERD diagrams software with powerful tools and ready design elements for Crow's Foot and Chen notations.

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.

Technical Drawing Software

Technical drawing or draft is a form of specialized graphic communication, exchange of ideas in industry and engineering. It is a visual representation of object with indication of dimensions and used material, constructed with maintaining the proportions between its parts. Technical drawings are constructed by architects, technologists, engineers, designers, drafters, and other technical professionals according to defined rules, specifications, internationally accepted standards and standardized notations allowing to make unambiguous, clear and understandable technical drawings. ConceptDraw DIAGRAM extended with Electrical Engineering solution, Mechanical Engineering solution, Chemical and Process Engineering solution from Industrial Engineering Area of ConceptDraw Solution Park is ideal technical drawing software. Its powerful drawing tools, predesigned vector objects, templates, samples are helpful for creation all kinds of Technical Drawings and Technical Diagrams, Electrical and Mechanical Schematics, Circuit and Wiring Diagrams, Structural Drawings, and many other.
