depicts relationships between data objects

|
|
depicts functions that transform the data flow

|
|
indicates how data are transformed by the system
|
|
|
indicates system reactions to external events
|
Detailed explanation-1: -The option is correct. System reactions to external events are represented by the state transition diagram. Using the state transition diagram the complete details of an object can be visualized.
Detailed explanation-2: -A state transition diagram is used to represent a finite state machine. These are used to model objects which have a finite number of possible states and whose interaction with the outside world can be described by its state changes in response to a finite number of events.
Detailed explanation-3: -There are two types of transitions: Internal transitions describe the reaction to an event that effects an activity, but no state transition. As a consequence, no entry or exit activities are executed. External transitions describe transitions that cause an object to enter or exit a state as a reaction to an event.
Detailed explanation-4: -State Transition Diagram are also known as Dynamic models. As the name suggests, it is a type of diagram that is used to represent different transition (changing) states of a System. It is generally used to graphically represent all possible transition states a system can have and model such systems.
