| Artifact: System Use Case Diagram |
 |
|
|
| Main Description | A System Use-Case diagram displays the relationships between consumers and providers of application services. Application services are consumed by actors or other application services and the Application Use-Case diagram provides added richness in describing application functionality by illustrating how and when that functionality is used. The purpose of the System Use-Case diagram is to help to describe and validate the interaction between actors and their roles with applications. As the architecture progresses, the use-case can evolve from functional information to include technical realization detail. Architectural system use-cases can also be re-used in more detailed systems design work. |
