Composite Structure Diagram
A Composite Structure diagram reflects the internal collaboration of Classes, Interfaces or Components (and their
properties) to describe a functionality. Composite Structure diagrams are similar to Class diagrams, but whilst Class
diagrams model a static view of Class structures, including their attributes and behaviors, Composite Structure diagrams
model a specific usage of the structure. You can use them to express run-time architectures, usage patterns and the
participating elements' relationships, which might not be reflected by static diagrams.
In a Composite Structure diagram, Classes are accessed as Parts or run-time instances fulfilling a particular role. These
Parts can have multiplicity, if the role filled by the Class requires multiple instances. Ports defined by a Part's Class
should be represented in the composite structure, so that all connecting Parts provide the required interfaces specified by
the Port. There is extensive flexibility, and a consequent complexity, that come with modeling composite structures. To
optimize your modeling, consider building Collaborations to represent reusable Patterns responding to your design
issues.
You generate Composite Structure diagram elements and connectors from the 'Composite' pages of the Diagram
Toolbox.
Example Diagram
This diagram shows a Collaboration used in a Composite Structure diagram to show a relationship for performing an
installation. Collaborations are often used to model common patterns.
