What is collaboration diagram?

A collaboration diagram, also known as a communication diagram, is a type of UML (Unified Modeling Language) diagram that illustrates the interactions and relationships between objects in a system. It focuses on the messages exchanged between objects and how they collaborate to achieve a particular functionality. Unlike sequence diagrams that emphasize the time sequence of messages, collaboration diagrams highlight the structural organization of the objects involved, making it easier to visualize their connections and interactions.
