Class diagrams

A class diagram provides a graphical representation of the structures and relationships of elements in an application.

For example, a class diagram can depict some or all of the components or elements in an application. You can use class diagrams to create your own context to examine, understand, collaborate, and design using a subset of the components or elements in an application.

Class diagrams use multiple variations of association relationships to indicate which classifiers must share data with other classifiers.
