Some components exist only at compile time, some exist only at link time, some exist only at run time and some exist at more than one time. Components can be classified by their type. They are related to component diagrams in that a node typically encloses one or more components.Ī component is a grouping of classes that work together closely. Deployment diagrams address the static deployment view of an architecture. A deployment diagram shows the configuration of run time processing nodes and the components that live on them. In the UML, deployment diagrams is used to visualize the static aspect of these physical nodes and their relationships and to specify their details for construction.ĭeployment diagrams are one of the two kinds of diagrams used in modeling the physical aspects of an object-oriented system.
At the edge of your system's software and hardware, you use deployment diagrams to reason about the topology of processors and devices on which your software executes. You use sequence diagrams, collaboration diagrams, statechart diagrams, and activity diagrams to specify the behavior of your software.
In the UML, you use class diagrams and component diagrams to reason about the structure of your software.
