5. Subsystem Interface The set of public operations forms the subsystem interface or Application Programming Interface (API) Includes operations but also their parameters, types, and return values Operation contracts are also defined (pre- and post-conditions) and accounted for by client subsystems – they can be considered part of the API

6. 6 Components vs Subsystems A Component are used to implement a package of classes defined in a subsystem A component defines a module in the architectural design Component types defined by component stereotypes include a Main program component, and Tasks Task components represent packages or subsystems with independent threads of control

11. Static versus Dynamic Architecture Information Subsystem Interfaces and dependencies provide static information Interaction models provide dynamic information Concurrency information can be specified on objection collaboration diagrams, sequence diagrams, and component diagrams

12. 12 Concurrency Adornment The concurrency of a class is a statement about its semantics in the presence of multiple threads of control. You can set the concurrency of a class to type Active The class will has its own thread of control. The method can be executing concurrently with other methods. You can display the concurrency for the class in the class diagram by selecting Show Concurrency from the class shortcut menu.

13. 13 Concurrency in Sequence Diagrams Synchronous method invocation for sequential execution

14. 14 Concurrency in Sequence Diagrams

15. 15 Concurrency in Sequence Diagrams Asynchronous method calls should be explicitly identified with the UML standard notation of a solid line with a half arrowhead. Asynchronous messages do not yield the current thread of control. Therefore, from the initiating object's viewpoint, there is no implied return message or waiting
