b) Database structures
c) ALL of the mentioned
d) None of the mentioned
View Answer
Explanation: None.
4. Forward engineering is not necessary if an existing software product is producing the correct output.
a) True
b) False
View Answer
Explanation: Forward engineering refers to taking a high-level model and using it to build a more complex lower-level implementation.
5. Which of the following is not an example of a business process?
a) designing a new product
b) hiring an employee
c) purchasing services
d) testing software
View Answer
Explanation: It is a part of development phase.
6. Which of the following is a data problem?
a) hardware problem
b) record organisation problems
c) heavy computational demands
d) loss of comments
View Answer
Explanation: Records representing the same entity may be organised differently in different programs.
7. When does one decides to re-engineer a product?
a) when tools to support restructuring are disabled
b) when system crashes frequently
c) when hardware or software support becomes obsolete
d) subsystems of a larger system require few maintenance
View Answer
Explanation: Re-engineering involves putting in the effort to make the system easier to maintain.
8. Which of the following is not a business goal of re-engineering ?
a) Cost reduction
b) Time reduction
c) Maintainability
d) None of the mentioned
View Answer
Explanation: No such goal is mentioned which is not a business goal, so option d is correct here.
9. Which of these benefits can be achieved when software is restructured?
a) Higher quality programs
b) Reduced maintenance effort
c) Software easier to test
d) All of the mentioned
View Answer
Explanation: The answer is self explanatory.
