What is the ―dynamic‖ model • A model that captures behaviour • Diagrams for dynamic modeling ● Interaction diagrams describe the dynamic behavior between objects ● State charts describe the dynamic behavior of a single object • Interaction diagrams ● Sequence Diagram: • Dynamic behavior of a set of objects arranged in time sequence • Good for real-time specifications and complex scenarios • State Charts ● A state machine that describes the response of an object of a given class to outside input (events) Winter 2009, Maheswaran Introduction to Software Engineering – ECSE321 Unit 6 – Analysis /54
Why do we need a dynamic model? • Understand the flow of events • Understand lifespan of classes • Refine the static model ● Add classes: •Events •Sequence diagrams are a source for more objects • Identify operations for the object model • Dynamic model will typically be incomprehensible to the customer!
