Node (UML)


A node in the Unified Modeling Language is a computational resource upon which UML artifacts may be deployed for execution.
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".

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".
