In detailed modeling, the classes of the conceptual design are often split into subclasses.In order to further describe the behavior of systems, these class diagrams can be complemented by a state diagram or UML state machine.MembersUML provides mechanisms to represent class members, such as attributes and methods, and additional information about them like constructors.VisibilityTo specify the visibility of a class member (i.e. They are also left-aligned and the first letter is lowercase.A class with three compartments.In the design of a system, a number of classes are identified and grouped together in a class diagram that helps to determine the static relations between them. They are left-aligned and the first letter is lowercase.*The bottom compartment contains the operations the class can execute. It is printed in bold and centered, and the first letter is capitalized.*The middle compartment contains the attributes of the class. The classes in a class diagram represent both the main elements, interactions in the application, and the classes to be programmed.In the diagram, classes are represented with boxes that contain three compartments-*The top compartment contains the name of the class. Class diagrams can also be used for data modeling. It is used for general conceptual modeling of the structure of the application, and for detailed modeling, translating the models into programming code. Class diagram is not only used for visualizing, describing, and documenting different aspects of a system but also for constructing executable code of the software application.The class diagram is the main building block of object-oriented modeling. It represents the static view of an application. You can edit this Entity Relationship Diagram using Creately diagramming tool and include in your report/presentation/website. The individual classes are represented just with one compartment, but they often contain up to three compartments.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 systems classes, their attributes, operations (or methods), and the relationships among objects.A Entity Relationship Diagram showing Class diagram- Leave Management system. Hierarchy of UML 2.5 Diagrams, shown as a class diagram.
