Explanation

Component diagrams show the static structure of the implementation model. A component diagram is presented as a collection of (static) declarative model elements, such as components, subsystems, and their relationships, connected as a graph to each other. Component diagrams can be organized into, and owned by implementation subsystems, which show only what is relevant within a particular implementation subsystem.

Use

The following structures are suitable for illustration in component diagrams.

• Implementation subsystems and their import dependencies.
• The implementation subsystems organized in layers.
• Components (source code files) and their compilation dependencies.
• Components (applications) and their run-time dependencies.
• Important structure of components, for example to illustrate a typical use of a component.
