The collaboration diagram represents the relationships between the objects.

The objects collaborate and operate together by communicating (passing messages) with each other. Through interacting together, objects may generate (usable) high-level functionalities. Collaboration is a set of named actions and systems which have connections to them. The aim of a collaboration diagram is to illustrate the systemic dimensions of a structure, i.e., how various lifelines link within the structure. The interactions among these elements are then used to build a model. They are the main information source used to establish class roles and interfaces.Ĭollaboration diagrams are developed by first determining the design elements required to incorporate the functionality of interface features. Designers can use collaboration diagrams to explain and identify the roles of objects performing a specific flow of events in a use case. They can demonstrate how objects communicate to execute a specific use case's actions or an aspect of a use case. Collaboration diagrams are also known as communication diagrams.
