Deployment Diagrams
Finally the way the individual components are deployed to a
hardware system can be described using the 
deployment diagram.
Because we decided to merge the different diagram types, the editor
contains a wide set of elements to be used (see also: Object diagrams
Component diagrams). Deployment diagrams
are defined on two levels: object or _instance level and class level.
For this reason, Poseidon for UML provides both nodes and instances of
nodes.
Diagram Elements
Nodes and 
Instances of Nodes - Represent the hardware
elements of the deployment system.
Components and
Instances of
Components - Represent software elements that are
deployed to the hardware system.
Links - Used to connect instances
of nodes or objects.
Dependencies - Exist between
components and can be specified by utilizing predefined or
user-defined stereotypes.
Associations - Used to display
communication relations between nodes. They can be specified by
utilizing predefined or user-defined stereotypes.
Objects, 
Classes, 
Interfaces - Components and nodes can
include objects, classes or interfaces.
