Working with UML class diagrams

A UML class diagram is a diagram that provides a static view of an application.
It shows some or all of the components or elements in an application and the relationships between them, such as inheritance and association. You can use class diagrams to visually represent and develop Java applications and Java EE Enterprise JavaBeans applications. Rational Application Developer also allows Web Service Description Language (WSDL) elements, such as WSDL services, port types, and messages to be shown on class diagrams. In Application Developer v7.5, enhanced support is provided for UML visualization of EJB 3.0 applications.

The content of a class diagram is stored in a file with a .dnx extension. The UML class diagram editor consists of an editor window that displays the current class diagram and a palette that contains individual drawers containing the elements that can be added to a class diagram.
