Entity Relationship Diagram - ERD - Software for Design
Chen ER Diagrams

One of the methods actively used in a real design of database structure is semantic modeling, which is a modeling of the data structure, based on the meaning of these data. Various types of ER diagrams are used as the tool of semantic modeling.

The first version of the entity-relationship model was proposed in 1976 by Peter Chen. In the future, many authors have developed their own versions of these models (Martin notation, IDEF1X notation, Barker notation, etc.). Irrespective from the notation, all versions of Entity-relationship diagrams are based on the same idea - image is always more visual than text description. ER diagrams use a graphical representation of the entity domain, their properties (attributes), and the relationships between entities.

The Entity-Relationship Diagram (ERD) solution from ConceptDraw Solution Park extends ConceptDraw DIAGRAM ector graphics and diagramming software with the ability to describe a database using the Entity-Relationship (Chen) model. Use it for design your ERDs and verify that ConceptDraw DIAGRAM offers the best ERD diagrams software tools for design element Chen notation.

UML Class Diagram Notation →

When it comes to system construction, a class diagram is the most widely used diagram. UML Class Diagrams is a type of static structure diagram that is used for general conceptual modeling of the systematics of the application. Such a diagram would illustrate the object-oriented view of a system. The object orientation of a system is indicated by a class diagram. It describes the structure of a system by showing the general issues,classes of a system, attributes, operations, interfaces, inheritance, and the relationships between them.UML Class Diagram Notation *
