Chapter 9, Problem 82E

Explanation of Solution

a.

List of stages in object-oriented decomposition:

• It concentrates on the objects and their relations within a problem.
• It contains four stages...

Explanation of Solution

b.

Characteristic of four stages in the object-oriented decomposition:

• Brainstorming stage:
  • The initial stage of design methodology is the brainstorming stage.
  • It is used to determine the problem to create a list of classes to solve the particular problem.
  • It is just like advertising the product before it launches into the market.
  • Brainstorming class requires that all participants must know about the problem before its starts; then only the participants will solve the problem in clear manner.
  • Hence, every team member creates the preliminary list of classes.
• Filtering stage:
  • The second stage of the design methodology is the filtering stage.
  • The filtering stage will analyze the list of classes produced by the brainstorming stage.
  • Find out whether there are any duplicate classes in this list or whether any classes are missed or combined in the list.
    • If the two classes in the list contain the common methods and fields, then these methods and fields are combined is called as combined class.
    • Example: Duplicate classes are referred as a people at different places using different names for the same idea...

Explanation of Solution

c.

Output of four stages in the object-oriented decomposition:

• Brainstorming stage:
  • The output of the brainstorming stage creates the preliminary list of classes to solve the particular problem.
• Filtering stage:
  • The output of the filtering stage is Class Responsibility Collaboration (CRC) cards for the list of classes that filtered out with some common relationship...

Explanation of Solution

d.

Stages of object-oriented decomposition:

“No”, each stage of the object-oriented decomposition is not independent.

Reason:

• The brainstorming stage produces the preliminary list of classes to solve the specific problem and the list of classes is passed as the input of the filtering stage...
