Attributes must be meaningful and are usually used with the visibility factor that describes the accessibility of an attribute.
You can simply add new attributes or derive new attributes from already listed attributes. Moreover, an abstract class should be written in italics.Īttributes are written in the middle compartment and list down all the properties of the object being modeled. It should be written in bold in the top compartment and start with a capital letter. The class name is important for graphical representation. The rectangle is divided into three compartments with the topmost being Class Name, then Attributes in the middle, and Operations in the bottom. There are three major parts of a class diagram as shown in the image below:Ī single rectangle is used to represent the class as shown above. Along with that, they are used for the analysis and design of an application and are also used in forward and reverse engineering. That is why they are frequently used in the modeling of object-oriented systems and are widely used during the construction of object-oriented systems.Ĭlass diagrams are one of the most important diagrams in coding as they form the basis for component and deployment diagrams and describe the responsibilities in a system. It is also used for describing, visualizing, and documenting different facets of a system.Ĭlass diagrams are the only UML diagrams that can be mapped directly with object-oriented languages.

This helps software engineers in developing the code for an application. A class diagram shows the classes, attributes, operations, and the relationship between them. A class diagram is a static structure that is used in software engineering.
