PART _ A
With an example, define a model. What purpose does it serve? Explain.
With a neat diagram, explain a class model of windowing systern.
Explain qualihed association with suitable example.
Explain the concept of work around with example.
Explain aggregation and composition with example.
What are nested states? Explain nested states with an example.
Consider a physical bookstore, such as in a shopping mall:
i) List three actors that are involved in the design of a checkout system.
Fig.Q2(b) is a partially completed state diagram for the control of a telephone answering
machine. The machine detects an incoming call after five rings and answers the call with a
prerecorded announcement. When the announcement is cornplete, the machine records the
caller's message. When the callerhangs up, the machine hangs up and shuts off. If someone
answers the telephone before five rings, the machine should do nothing. Distinguish between
calls in which the telephone is answered on the first ring and one call that rings five times.
Draw and explain state model or diagram. Place the following in the diagram: call detect,
answer call, play announcement, record message, caller hangs up, announcement complete.
