Crow’s Foot Notation

Nowadays are used large number of data modeling techniques, but the most common is Entity-Relationship Diagram (ERD). Several notations are used for ERDs, the most popular is Crow’s Foot notation or IA (Inverted Arrow) notation proposed by Gordon Everest. With its help, it is convenient to create clear and understandable diagrams with large number of attributes.

Crow’s Foot notation suggests the use of boxes to represent the entities and the lines to illustrate the relationships between these entities. Each box contains the name of the entity (noun, obligatory unique within this model) and also its attributes. Each connection line has a name indicated by verb, on the both ends of it are placed the special graphical symbols, which indicate the cardinality and modality. The cardinality determines the counts of relationships, such as one-to-many, one-to-one, many-to-many; one is represented by a vertical straight line and many - by crow's foot symbol. Modality of relationship can be specified by one of two values: one that is indicated by the straight line, or zero that denotes on the optionality of relationship and is represented as the empty circle.

Crow’s Foot Notation solution extends ConceptDraw PRO software with powerful drawing tools, samples and library of predesigned vector Crow's Foot notation icons to help you easy describe the databases using the Entity-Relationship models and design professional-looking ER diagrams based on Crow's Foot notation.


There is 1 stencil library containing 17 vector graphics in the Crow’s Foot Notation solution.
