UML Deployment Diagram

Deployment Diagram⌘

• Describes the hardware used in system implementations, execution environments and artifacts deployed on the hardware.

Node⌘

• A Node is computational resource upon which Artifacts may be deployed.
• Nodes may have complex internal structure (can only consist of other nodes)
• Two types of nodes:
  • Device (physical machine components) - e.g. application server, client workstation, mobile device
  • Execution Environment (software systems) - e.g. OS, workflow engine, database system, J2EE container

Artifact⌘

• An artifact represents some item of information that is used or produced by a software development process or by operation of a system.
• An artifact represents concrete elements in the physical world.
• Examples of artifacts: model files, source files, scripts, executable files, database tables, word-processing documents, and mail messages.

Communication Path⌘

• A communication path is an association between two nodes, through which they are able to exchange signals and messages.
• It usually represents physical connection between devices or some protocol between execution environments.

Deployment⌘

• A deployment is a dependency relationship which describes allocation (deployment) of an artifact to a deployment target.

Deployment Specification⌘

• A deployment specification specifies a set of properties that determine execution parameters of a component artifact that is deployed on a node.

Connection between Node, Component and Artifact⌘
