PART B — (5  13 = 65 marks)
11. (a) Define Unified Process Model? Exemplify the iterations, outcomes and
workflow in unified Process Model with neat sketch.
Or
(b) Deliberate different notations of UML diagrams in detail.
12. (a) Explain different categories of conceptual classes with examples and
discuss the three strategies to find a conceptual class.
Or
(b) Describe in detail, the Associations, Attributes, Aggregation and
Composition give suitable example.
13. (a) Consider the Library management system. It should provide the facility
to issue the book, to calculate the fine during book return, the placement
of the books on the shelfs, adding new books to the shelfs and removing
old books from the shelfs. Draw the activity diagram with swim lanes for
each and every components of the above scenario.
Or
(b) Consider a House keeping system in a five star hotel. Draw a sequence
and collaboration diagram for the given scenario.
14. (a) Illustrate and provide an interface for creating families of related or
dependent objects without specifying their concrete classes using factory
method.
Or
(b) Elucidate Creator pattern and controller pattern with real time
examples.
15. (a) Explicate in detail the various testing strategies and the impact of object
orientation on testing.
Or
(b) Illustrate with neat sketch the software development life cycle of
object-oriented system.

PART C — (1  15 = 15 marks)
16. (a) Consider a distributed information system for accident management. It
includes many actors such as FieldOfficer, who represent the police, fire
officers who respond to accidents, and Dispatcher, the police officer
responsible for answering 911 calls and dispatching resources to an
accident. FRIEND supports both actors by keeping track of incidents,
resources, and task plans. The FieldOfficer and the Dispatcher interact
through different interface – FieldOfficer interacts FRIEND through a
mobile personal assistant, and Dispatcher access FRIEND through a
workstation. Identify suitable process model for the above project and
justify your answer.
Or
(b) To buy a book electronically from chapters.com, a customer needs to
select the book from a list provided by Chapters’ e-Commerce system,
provide credit card information to the system, then the system gets
authorization from the bank for the payment, and – if positive – confirms
the sale. The order is then sent to the orders department and when the
book becomes available, it is shipped to the customer.
Also, the order department charges the customer’s credit card by
informing the bank of the amount. Draw a sequence diagram that models
this process. Make sure that the model has all relevant actors and the
interactions between them. Do show explicitly the time intervals when
different actors actively participate in the modelling process.

to Inception.
(OR)
b) With an illustration, explain the class hierarchies. Also state the guidelines

Part – C (1×15=15 Marks)
16. a) A library has books, journals and laptops. Undergraduate students can borrow
only books and journals. Post graduate students can borrow only journals
and laptops. A maximum of three books, two journals and one laptop will
be issued per student. If they return these items beyond ten days, a fine of
Rs. 10 per day is levied for each book/journal. However, for late return of
laptop a fine of Rs. 1,000 is levied. The librarian also periodically takes stock
of books, journals and laptops and generates the report of lent out items and
lost items. Construct the necessary activity diagrams for the operations
carried out by the librarian.
(OR)
b) A mobile device has to be fitted with an alarm clock. The clock has a display
unit to show the time of day. Using buttons, the user can set the hours and
minutes fields individually. It supports a 24-hour display. It is possible to
set one or two alarms. When an alarm fires, it will sound some noise. The
user can turn it off, or choose to ‘snooze’. If the user does not respond at all
the alarm will turn off itself after 2 minutes. ‘Snoozing’ means to turn off
the sound, but the alarm will fire again after some minutes of delay. This
‘snoozing time’ is pre-adjustable. Identify the functional requirements for the
clock and model it with a use case diagram.
