Determine the behavior for which the realization and implementation are specified.Steps for creating a Collaboration Diagram The messages sent during the same call are denoted with the same decimal prefix, but with different suffixes of 1, 2, etc. In the collaboration diagram, each message constitutes a sequence number, such that the top-level message is marked as one and so on.To support the identification of objects participating in the use case.To model different scenarios within the use case or operation, involving a collaboration of several objects and interactions.To capture the interactions that represent the flow of messages between the objects and the roles inside the collaboration.To model the mechanism inside the architectural design of the system.To model collaboration among the objects or roles that carry the functionalities of use cases and operations.The collaboration diagrams are best suited for analyzing use cases.įollowing are some of the use cases enlisted below for which the collaboration diagram is implemented: Both the sequence and collaboration diagrams represent the same information, but the way of portraying it quite different. The collaborations are used when it is essential to depict the relationship between the object. The receiver must understand the message. The messages are sent from the sender to the receiver, and the direction must be navigable in that particular direction. It is represented by a labeled arrow, which is placed near a link. Messages: It is a communication between objects which carries information and includes a sequence number, so that the activity may take place. The link helps an object to connect with or navigate to another object, such that the message flows are attached to links. It portrays a relationship between the objects through which the messages are sent.
