Messages sent during the same call have the same decimal prefix but suffixes of 1, 2, etc.

Each message in a collaboration diagram has a sequence number.

Support the identification of objects (hence classes) that participate in use cases.

Model alternative scenarios within use cases or operations that involve the collaboration of different objects and interactions.

Capture interactions that show the messages passing between objects and roles within the collaboration.

Model mechanisms within the architectural design of the system.

Model collaborations between objects or roles that deliver the functionalities of use cases and operations.

So, here are some use cases that we want to create a collaboration diagram for: In addition, it is difficult to show additional descriptive information such as timing, decision points, or other unstructured information that can be easily added to the notes in a sequence diagram. However, if the number of objects and messages grows, the diagram becomes increasingly hard to read. Specifically, they tend to be better suited to depicting simpler interactions of smaller numbers of objects. Sequence diagrams and collaboration diagrams express similar information, but show it in different ways.īecause of the format of the collaboration diagram, they tend to better suited for analysis activities (see Activity: Use-Case Analysis). Unlike a sequence diagram, a collaboration diagram shows the relationships among the objects.

Objects collaborate by communicating (passing messages) with one another in order to work together.Objects are able to produce (usable) high-level functionalities by working together.Each object (responsibility) partially supports emergent functionalities.A Collaboration between objects working together provides emergent desirable functionalities in Object-Oriented systems.A Collaboration defines a set of participants and relationships that are meaningful for a given set of purposes.

They collaborate in performing some task. A Collaboration is a collection of named objects and actors with links connecting them.It is an international award-winning UML modeler, and yet it is easy-to-use, intuitive & completely free.

Visual Paradigm Community Edition is a UML software that supports all UML diagram types. They are the primary source of information used to determining class responsibilities and interfaces. Along with sequence diagrams, collaboration are used by designers to define and clarify the roles of the objects that perform a particular flow of events of a use case. Collaboration diagrams ( known as Communication Diagram in UML 2.x) are used to show how objects interact to perform the behavior of a particular use case, or a part of a use case.
