CS1402 - OBJECT ORIENTED ANALYSIS AND DESIGN


PART A – (10 x two = 20 Marks)


1. Mention the OOSD life cycle
2. What is dynamic binding? When does 1 go for it?
3. What is unified approach? Does it specify a methodology?
4. What is meant by dynamic modeling?
5. Define aggregation.
6. Name few diagrams in Booch Methodology.
7. What is meant by Database interface? provide an example.
8. What is a protocol and its function?
9. Discuss the impact on object orientation on testing.
10. Continuous testing cured the last minute crunch comment on it.

PART B - (5 x 16 = 80 Marks)

11. Why is object orientation started finding place in system development? elaborate its
major advantages and methodologies? How to design objects, relationships and
associations? How is object persistence helpful and how to store only the persistent
attributes?

12. (a) (i) Outline OMT functional model. Also provide OMT data floe diagram primary
symbols.
(ii) What is the strength of Jacobson methodology emphasizing the 2 key
concepts in it?

Or

(b) Why do we need to model a problem? What is UML and define its
importance? How is the dynamic behaviors expressed using different diagrams
as per Booch?

13. (a) define the non phrase approach for identify tentative classes in a issue
domain. Why are classes, responsibilities and collaborations useful? Identify the
three steps in CRC process.

Or

(b) elaborate the guidelines for defining attributes? How would you identify a super-
sub class structure?

14. (a) What is coupling? While designing software programs, what precautions will 1
bore in mind. Tabulate kinds of coupling among objects or components.

Or
(b) elaborate a few characteristics of a bad design? In a networking environment
what precautions 1 has to consider to design associations. If server-client
architecture is adapted.

15. (a) define the various testing strategies. How to develop test plans guided by
Thomas.

Or
(b) Sketch the guidelines for developing quality assurance test cases defined by
Freedman and Thomas adapted for the UA. elaborate the steps involved to make
the testing successful?
