Quiz Week 13 Object DMBS
Team G38 Connor Ferris, Anand Rajan
Example
“Consider the challenge posed by an airborne warning and control system (AWACS) (Figure 1) that divides database processing between real-time,
embedded in-memory database systems (IMDSs) residing in one or more data acquisition modules, and an enterprise-class application and DBMS
that run on a high-powered server and are responsible for carrying out primary mission tasks such as surveillance, communication, and command
and control”
TL;DR -> AWACS uses DBMS to do cool stuff.
Question 1
Which of the following requires object
database technology?
A. Storing employee picture on disk
B. Retrieving an employee picture
C. Retrieving and processing an employee
picture together with simpler data
C. Retrieving and processing an employee
picture together with simpler data
A and B could be accomplished with a hard
drive and GIMP.

from external world. This properties is called:
A. Abstraction
B. Encapsulation
C. Inheritance
D. Polymorphism
B. Encapsulation
Question 4

B. Encapsulation
C. Inheritance
D. Methods (i.e. procedures)

Question 5
Which of the following do not apply to today’s object relational
DBMS?
A. Calls to functions that process media data are part of the
database
language
B. Specialized storage structures are provided
C. Reliability is of no concern
D. Combined access to complex data and relational data is
optimized
C. Reliability is of no concern
Discussion Question
Which object DBMS architecture do you think will dominate in five
years?
Mannino says SQL:2008 or Oracle g11 and beyond
following the object-relational approach.
