Node (UML)

Two execution environments instances nested in a device instance

A node In the Unified Modeling Language (UML) is a computational resource upon which UML artifacts may be deployed for execution. [1]

There are two types of nodes: device nodes and execution environments.

Execution environments can be nested. Nodes can be interconnected through communication paths to define network structures. A communication path is an "association between two DeploymentTargets, through which they are able to exchange signals and messages".[1]

Usage

When modeling devices, it is possible to model them in several different ways:

Use tagged values to specify characteristics of devices / execution environments, for instance "Memory=2GB", "Disk Space=32GB", "Version=2.5.1".
