質問 # 32
In a use case, which is one of the two commonly used relationships?
- A. Extend
- B. Inherit
- C. Identify
- D. Distribute
正解：A
解説：
There are two commonly used relationships between use cases:
Extend: allows for the insertion of additional behavior into a use case. The use case that is being extended must be completely functional in its own right and must not depend on the extending use case for its successful execution. This relationship may be used to show that an alternate flow has been added to an existing use case (representing new requirements).
Include: allows for the use case to make use of functionality present in another use case. The included use case does not need to be a complete use case in its own right if it is not directly triggered by an actor. This relationship is most often used either when some shared functionality is required by several use cases or to abstract out a complex piece of logic.
