Note: Answer all questions. Kindly note that answers for 10 marks questions should be
approximately of 400 words. Each question is followed by evaluation scheme.
Question. 1. Explain State charts and Activity Diagrams with
examples.
Answer:A program with a graphical user interface is a good example of an event-driven system, as
the program mustreact to userinputevents.The timingandtype of these eventsisunpredictable.A
server is another good example because the timing and types of client requests can be
unpredictable.
Statechart Machines
Harel introduces the concept of a statechart machine as an abstract model of a reactive system. A
statechart machine is an example of a finite-
Question. 2. What is Booch methodology? Explain its macro and
micro development processes.
