Deck 16: Object-Oriented Technologies

Question 1

Which of the following is true of the procedure view?

A)It consists exclusively of information.
B)It contains nine primary procedures.
C)It converges with the information view.
D)It involves changing or manipulating information.

Answer 1

D
Explanation: The procedure view in the traditional technology approach contains all the procedures within a system.A procedure manipulates or changes information.

Question 2

Why is it important to use multiple classes for large amounts of information?

A)To better manage the information and prevent multiple system problems from taking place
B)To simplify the process of combining information from multiple classes
C)To represent mixed categories of classes
D)To enhance the degree of detail in the information

Answer 2

A
Explanation: Information decomposition refers to breaking down information and procedures for ease of use and understandability.It is a better way to structure one's information system.Placing all information and procedures for an entire system into a single class is a bad system design and would lead to multiple system problems.
