Background 
Collaboration Diagrams are one of the two forms of object interaction diagram used in
the UML. The other is the Sequence Diagram (See Standards:
Sequence Diagrams). These diagrams present the same information but with
different perspectives. In Rose a collaboration diagram can be converted into a
sequence diagram by using the menu option Browse: Create Sequence Diagram (F5). The
two diagrams are than automatically kept synchronized by Rose.
A collaboration diagram shows a set of objects, the links between them and the messages
sent and received by the objects. For the standards applicable to the items
appearing on a collaboration diagram see Standards:
Instances Overview.
In most cases, you use a collaboration diagram to show how objects interact to perform
the behavior of a particular use case, or part of a use case (See Standards: Use Case Realizations).
Collaboration diagrams may also be used to demonstrate / explore how particular classes
or packages fulfill their responsibilities (See Standards:
Design Packages).
Naming Standards
Collaboration Diagram names should begin with an upper case letter. The naming
standards for specific collaboration diagrams are defined for their containing model items
(See Standards: Design Packages and Standards: Use Case Realizations).
Documentation
Where necessary the purpose of the diagram can be described in its documentation field.
This is optional for standard diagrams but mandatory for any additional (non-standard)
collaboration diagrams added to packages or use case realizations (See Standards: Design Packages and Standards: Use Case Realizations).
Rose Documentation
Although diagrams do not have a specification they do have a documentation field. If
you select the diagram in the Browser then you will see the diagram's documentation in the
documentation window. This can be edited directly in the documentation field. |
