Class to Object Diagram Example - Order System This small class diagram shows that a university Department can contain lots of other Departments and the object diagram below instantiates the class diagram, replacing it by a concrete example. The following Order Management System shows their relationships. The best way to illustrate what an object diagram look like is to show the object diagram derived from the corresponding class diagram. They are be useful to explain smaller portions of your system, when your system class diagram is very complex, and also sometimes modeling recursive relationship in diagram. Before you create a class diagram, you might create an object diagram to discover facts about specific model elements and their links, or to illustrate specific examples of the classifiers that are required.Īn object diagram shows this relation between the instantiated classes and the defined class, and the relation between these objects in the system.During the analysis phase of a project, you might create a class diagram to describe the structure of a system and then create a set of object diagrams as test cases to verify the accuracy and completeness of the class diagram.The use of object diagrams is fairly limited, mainly to show examples of data structures.
