Guidelines: Component Diagram
Topics
Explanation
Component diagrams show the structure of components, including classifiers
that specify components, and artifacts that implement them.
They can also be used to show the high level structure of the Implementation
Model in terms of Implementation Subsystems, and relationships between Implementation
Elements.
Use
The most important use of the component diagram in RUP is to show the high
level structure of the Implementation Model. Specifically:
A secondary use of the component diagram is to show:
Note that the RUP emphasizes the use of the Component Diagram for modeling
Implementation Subsystems, significant Implementation Elements, and their relationships.
However, a component diagram that shows UML components and the classifiers that
specify those components, can also be used in the Design Model, using the UML
component to represent Artifact: Design Subsystem. See Guidelines:
Design Subsystem for more on this topic.
