Explanation of Solution

Class Responsibility Collaboration (CRC) card for zoo database:

Brainstorming stage:

  • The initial stage of the design methodology is the brainstorming stage.
  • It is used to determine the problem to create a list of classes to solve the particular problem.
  • Brainstorming for class requires that all participants must know about the problem before its starts; then only the participants will solve the problem in clear manner.
  • The problem to design the zoo database.
    • To create a list of classes for the zoo database.
    • The classes are related to the zoo database such as animal name, cage number, animal family name, data of birth, sex of animal, date brought, food.

animal_name

cage_number

animal_family_name

date_of_birth

sex

date_brought

food

Filtering stage:

  • The second stage of the design methodology is the filtering stage.
  • The brainstorming is the first state which creates two classes of list for the same process.
  • Then filtering stage will analyze the list of classes produced by the brainstorming stage.
  • The problem to design the zoo database.
    • To filter out the classes from a list of classes for the zoo database.

animal

date_of_birth

cage_number

list_of_animal

food_for_animal

sex

animal_name

Scenarios stage:

  • The third stage of the design methodology is the scenario stage.
  • It determines the behavior of each classes in the list.
  • The behavior is referred to as the responsibilities because each class is responsible for its behavior.
  • The problem to design the zoo database.
    • To design the CRC cards from the listed filtered classes for the zoo database...
