UML robustness diagrams describe the flow of information and components involved in a complex system. UML robustness diagrams are used throughout the functional architecture documentation to describe the various products and components necessary to implement specific capabilities within the BMC BladeLogic Automation Suite value paths.

Each capability is divided into Actors (a person), Boundaries (typically a graphical user interface or a console), Entities (a database, or other external user artifact in the system, such as a server), and Controls (usually a BMC product). Arrows between the various components indicate the flow of information between the components. The following symbols are used:



Actor — User role that interacts with a component in the system

Boundary — Component that represents an interface with which Actors interact

Entity — Domain objects within the system that typically present a persisted state of that object

Control — Components that connect Boundary and Entity components and implement some logic to manage the interaction between them
