It describes a particular aspect of the entire application.įirst of all, Order and Customer are identified as the two elements of the system. The following diagram is an example of an Order System of an application. At the end of the drawing it should be understandable to the developer/coder.įinally, before making the final version, the diagram should be drawn on plain paper and reworked as many times as possible to make it correct. Use notes whenever required to describe some aspect of the diagram. Responsibility (attributes and methods) of each class should be clearly identifiedįor each class, minimum number of properties should be specified, as unnecessary properties will make the diagram complicated. The name of the class diagram should be meaningful to describe the aspect of the system.Įach element and their relationships should be identified in advance. The following points should be remembered while drawing a class diagram − A collection of class diagrams represent the whole system. It is very important to learn the drawing procedure of class diagram.Ĭlass diagrams have a lot of properties to consider while drawing but here the diagram will be considered from a top level view.Ĭlass diagram is basically a graphical representation of the static view of the system and represents different aspects of the application. The purpose of the class diagram can be summarized as −Īnalysis and design of the static view of an application.īase for component and deployment diagrams.Ĭlass diagrams are the most popular UML diagrams used for construction of softwareĪpplications.
It is the most popular UML diagram in the coder community. UML diagrams like activity diagram, sequence diagram can only give the sequence flow of the application, however class diagram is a bit different. Class diagrams are the only diagrams which can be directly mapped with object-oriented languages and thus widely used at the time of construction.
The purpose of class diagram is to model the static view of an application. It is also known as a structural diagram. The class diagrams are widely used in the modeling of objectoriented systems because they are the only UML diagrams, which can be mapped directly with object-oriented languages.Ĭlass diagram shows a collection of classes, interfaces, associations, collaborations, andĬonstraints.

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.Ĭlass diagram describes the attributes and operations of a class and also the constraints It represents the static view of an application.
