Component Diagram |
A component diagram shows a collection of declarative (static) model elements, such as components, and implementation subsystems, and their relationships. |
Topics
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.
