Understanding how different parts of a system interact is essential for modeling complex behaviors in software design. In this guide, we’ll cover what an Interaction Overview Diagram is, its key notations, and a step-by-step process on how to draw one. You’ll also explore the benefits of using these diagrams and learn when to use them effectively in system modeling.
Interaction Diagram Definition A UML Interaction Diagram is a type of behavioral diagram used to visualize how objects in a system interact through the exchange of messages. It focuses on the dynamic behavior of a system by showing what happens, when it happens, and which components communicate during a specific process or use case. Interaction diagrams capture the “conversation” between objects, helping designers and developers understand how parts of a system collaborate to achieve a goal.
