Component diagram
A component diagram (English component diagram ) is one of the 14 chart types in the Unified Modeling Language ( UML), a modeling language for software and other systems.
The component diagram is a structural diagram. It shows a particular view of the structure of the modeled system. The presentation typically includes on components with their interfaces or ports. It also shows how components are connected via connectors and dependency relationships. In order to represent the interior of a component, a component diagram notation often shows elements that otherwise appear especially in class or composite structure diagrams, for example, classes or parts.
The component diagram is mainly used in software development for the modeling of component-based software systems.
