H�T�Mo�0���>v�! Example Class and Object Diagrams The following diagram shows an object diagram with its defining class diagram inset, and it illustrates the way in which an object diagram may be used to test the multiplicities of assignments in class diagrams. In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects. Key Areas Covered 1. Duration: 1 week to 2 week. What is Class Diagram – Definition, Functionality 3. Each object diagram shows a set of objects and their inter-relationships at a point in time. For example, we refer a class, an object, a component, or a deployment node as classifiers in UML since they define a common set of properties. Similarly, in software engineering, a model represents a software product. Please mail your requirement at hr@javatpoint.com. It incorporates data values and attributes of an entity.
