( Common to Computer Science & Engineering and info
Technology)
Time: three hours Max Marks: 80
ans any 5 ques.
All ques. carry equal marks
? ? ? ? ?
1. (a) Contrast: data model Vs. object model.
(b) Consider any 3 object oriented programming languages. Enumerate any
six contrasting features comparatively.
(c) elaborate the basic features of object orientation? discuss briefly. [5+6+5]
2. (a) How is association modeled as a class?
(b) discuss the antisymmetric and transitive properties of aggregation.
(c) How is generalization/specialization contrasted with more code reuse? State
Liskov’s substitution principle.
(d) elaborate the principles of modeling? [4x4=16]
3. (a) provide examples for how named, anonymous, multiple and orphan instances are
depicted in UML notation?
(b) elaborate the different elements in UML that may have instances. How do you
denote object state in UML? provide example.
(c) Enumerate the steps to model concrete instance. [6+6+4]
4. (a) Illustrate the subsequent modeling problems with class diagrams.
i. Modeling simple collaborations
ii. Modeling logical database schema.
(b) elaborate the contents in class diagrams? [12+4]
5. (a) Create an instance sequence diagram that indicates what happens when you
successfully send a fax. That is, model the object interactions in the best-case
scenario of the “send fax” use case of a fax machine. Include objects for the
sending machine, the receiving machine, and a central exchange that routes
faxes and phone calls.
(b) elaborate the contents and common uses of interaction diagrams? describe
synchronous and asynchronous message. [10+6]
6. (a) describe interaction. Briefly discuss about links in interactions.
(b) Enumerate the steps to model flow of control in interactions.
(c) Briefly discuss about use cases. Enumerate the steps to model the behavior
of an element. [5+5+6]
7. (a) Enumerate the steps to model the following:
i. family of signals
ii. exceptions
(b) discuss the 4 types of events modeld by UML. [6+10]
8. Enumerate the steps to model the subsequent. Illustrate UML diagrams and discuss
briefly.
(a) Modeling processes and devices.
(b) Modeling distribution of components. [16]
