ERD Symbols and Meanings

Entity Relationship Diagram (ERD) is a popular software engineering tool for database modeling and illustration the logical structure of databases, which uses one of two notations - Chen's or Crow’s Foot. Crow's foot notation is effective when used in software engineering, information engineering, structured systems analysis and design. Each of these notations applies its own set of ERD symbols. Crow's foot diagrams use boxes to represent entities and lines between these boxes to show relationships. Varied shapes at the ends of lines depict the cardinality of a given relationship. Chen's ERD notation is more detailed way to represent entities and relationships. ConceptDraw DIAGRAM application enhanced with all-inclusive Entity-Relationship Diagram (ERD) solution allows design professional ER diagrams with Chen's or Crow’s Foot notation on your choice. It contains the full set of ready-to-use standardized ERD symbols and meanings helpful for quickly drawing, collection of predesigned ERD samples, examples and templates. ConceptDraw Pro is a great alternative to Visio for Mac users as it offers more features and can easily handle the most demanding professional needs.

Entity Relationship Diagram Symbols

The semantic modeling method nowadays is successfully applied in database structure design. It is effective method of modeling the data structures, which is based on the meaning of these data. As a tool of semantic modeling, there are used different types of Entity-Relationship Diagrams. Entity Relationship Diagram (ERD) is applied to visually and clearly represent a structure of a business database. The main components of ERDs are: entity, relation and attributes. An entity is a class of similar objects in the model, each entity is depicted in the form of rectangle and has the name expressed by a noun. Relation is shown in the form of non-directional line that connects two entities. There are several notation styles used for ERDs: information engineering style, Chen style, Bachman style, Martin Style. The Entity Relationship Diagram symbols used for professional ERD drawing are predesigned by professionals and collected in the libraries of the Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM software.

Pyramid Diagram

Pyramid diagram is a chart used to visualize the data in a hierarchical (pyramid-like) structure and depict the foundation-based relationships. Pyramid diagram looks like a triangle divided by lines into several sections (layers) and can be oriented up or down, and represented in 2D or 3D view. 2D Pyramid diagrams are a great way to illustrate the hierarchical structure, 3D Pyramids are equally good to represent the class stratification and hierarchy.

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.
