|
| | A) | A staff member need not be associated with any grades, or it can be associated with an indeterminate number of grades; a grade must be associated with one or more staff members. |
| | B) | A grade cannot be associated with a staff member but a staff member can be associated with a grade. |

|
|
22 | |
Why is it often difficult to determine the most appropriate choice of responsibilities for each class? |
| | A) | Because there may be several alternatives that appear equally justified. |
| | B) | Because the developers may not know enough about how the users want the system to be designed. |
| | C) | Because members of the development team are often lazy and avoid responsibility as much as they can. |
|
|
23 | |
The requirements of different use cases may suggest different operations for the same class. How do we resolve this? |
| | A) | We should split the class so that there is one for each use case, and model each class with the particular operations required for its use case. |
| | B) | We should include in the class all the operations that are suggested by all the use cases. |
| | C) | We should model the class with only that subset of operations that applies to all use cases. |
|
|
24 | |
Which of the following is an advantage of the use of a control class in realizing a use case? |
| | A) | A control class prevents users from being able to change the way that the entity classes work. |
| | B) | A control class reduces the need for entity classes to know anything about other entity classes unless this is directly relevant to their own responsibilities. |
