This Interaction Overview Diagram Model is a type of UML diagram used to capture a system's interactive behavior. Interaction diagrams describe the flow of messages within a system and provide context for one or more lifelines. Furthermore, interaction diagrams can represent ordered sequences within a system and visualize real-time data using UML. Each diagram type focuses on a distinct aspect of a system's behavior or structure. Look below for more information on the fundamentals of each diagram and how you can use them.
