Here you want question papers of Object Oriented Database Management System Exam of DOEACC B Level Course, so I am giving following papers:

DOEACC B Level Course Object Oriented Database Management System Paper I
1.
a) Abstraction is a fundamental human capability that permits us to deal with complexity.
Justify this statement.
b) In object oriented analysis and design, aggregation is considered as a special form of
association. Explain with an example.
c) Give reasons why it is necessary to override a feature in object oriented programming.
d) How does the concept of an object in the object oriented model differ from the concept of an
entity in entity relationship model?
e) What is the meaning of persistent and transient Objects in the object oriented databases?
Can a single class have both types of instances in object oriented databases?

(7x4)

2.
a) Prepare an Object diagram for a graphical document editor that supports grouping, which is
a concept used in a variety of graphical editors. Assume that a document is composed of
several sheets. Each sheet contains drawing objects, including text, geometrical objects and
groups. A group is simply a set of drawing objects, possibly including other groups. A group
must contain at least two drawing objects. A drawing object can be a direct member of at
most one group. Geometrical objects include circles, ellipses, rectangles, lines and squares.
b) Write the necessary steps which are required to implement an “Object Model”.
c) Differentiate between overloading and overriding of methods in object oriented programming
with suitable examples. Explain using C++ code.
(8+6+4)

3.
a) For which category of application, the use of object data management is more appropriate?
State any three relevant application pertaining to the use of object data management principles.
b) Enumerate the strengths and weaknesses of object oriented database management system.

and interoperation of distributed objects.
b) What is the meaning and type of distributed database? Define the term Distributed DBMS.
Explain the objectives of distributed databases.
(8+10)
5.
a) With neat sketch, explain the architecture of typical data mining system.
b) What is a database authorization? How database authorization is done in relational
database management system?

Processing (OLAP).
(8+6+4)

6.
a) SQL Extension and Extension to an OO Programming are two approaches used for object
query language. Compare and contrast between “SQL Extension” and “Extension to an OO
programming language”.
b) Explain, how the concept of data identity in relational database management system differs
from the concept of Object identity in object oriented database management system.
c) What is Object Management Group (OMG) reference model? Explain the responsibilities,
purposes and major components of OMG reference model.
(4+6+8)

7.
a) Differentiate the following Database concepts:
i) Remote Update Vs. Distributed Update
ii) Remote Transaction Vs. Distributed Updates.
