Document Summary

Event-driven states of objects and the transitions among states. Data-driven activity diagram (insulin case study) activity diagram. These model the behaviour of the system in response to external and internal events. They show the system"s responses to stimuli so are often used for modelling real-time. State machine models show system states as nodes and events as arcs between those nodes. When an event occurs, the system moves from one state to another. Statecharts are an integral part of the uml and are used to represent state machine systems. models. Sequence diagrams are part of the uml and are used model the interactions between the actors and the objects within a system. Modelling user interactio is important as it helps too identify user requirements. Modeling system-to-system interaction highlights the communication problems that may. Modeling component interactio helps us understand it proposed system structure is likely to deliver the required system performance and dependability.
