Important information about System Architecture Diagrams:
PTC introduced the System Architecture Diagram to cover the short comings of previous versions of UML for the real-time environment. Now that UML 2.0 has introduced the Composite Structure Diagram, the System Architecture Diagram is no longer required. As such, the System Architecture Diagram remains in Modeler for backward compatibility, but it will not be further developed in Modeler: for example, you cannot apply iconic Stereotypes to the System Architecture Diagram symbols.
We recommend that you now model your system architecture using Composite Structure Diagrams, in accordance with UML 2.0. To help you migrate your System Architecture Diagrams to Composite Structure Diagrams, Modeler includes the System Architecture Migration Utility.
For information about Composite Structure Diagrams, see Overview of the structure diagram.
For information about the System Architecture Migration Utility, see Overview of System Architecture Migration utility.
The System Architecture Model allows you to define architectural solutions to the level of Bus, Board and Disk. A series of System Architecture Diagrams describes the physical distribution of the system, showing processing and interface nodes plus the connections between them. Actors initiate processing activity in the System Architecture Model by sending Event messages to Subsystems and Interface Devices.
For information about System Architecture Modeling in Modeler, see System architecture overview.
You can view the System Architecture Model part of a model through the System Architecture Model folder in the Relationships pane.
The following sections provide information about the item and diagram types that are used in the System Architecture Model. For more information about a diagram or item, click it.
