Entity Relationship Software

Entity Relationship Diagram

ERD is a major data modelling tool which can help to organize your project's data into the entities and to define the relashionships between these entities.

It is convenient to design ER Diagrams using ConceptDraw DIAGRAM diagramming and vector drawing software extended with the Entity-Relationship Diagram (ERD) Solution from the Software Development Area for ConceptDraw Solution Park. This solution supports Chen's and Crow’s Foot notations that are often used to describe database structure.

In a Chen's notation, entities are represented by rectangles with the entities names inside and relationships are represented by diamonds. The attributes are drawn as ovals and are connected with a line to exactly one entity or relationship set.

ERD Software. Chen's notation

Example 1. Entity Relationship Software. Chen's notation

Another type of notation is known as Crow's Foot notation. Fundamentally it is very similar to Chen's notation and differs by designations, are used the boxes to represent entities and the lines between them to represent relationships. The attributes of entity are drawn in the box that represents this entity.
