Unit 19

 The use case diagram ... 

• A. Specifies the functional decomposition of a system 

• B. Comprises classes and objects 

• C. Specifies who performs which tasks with a system that is going to be developed 

• D. Models the time flow within a system

What are the two broad categories of diagrams in UML 2.0? 

• A. Structural and Use Case 

• B. Behavioral and Logical 

• C. Structural and Behavioral 

• D. Logical and Physical

The main purpose of the use case narrative is to: 

• A. Describe a use case from a use case diagram 

• B. Select the involved actors only 

• C. specify the required functions in the project 

• D. create a plan B for use case

Which of the following questions are useful when identifying the involved actors of a use case diagram? 

• A. Who needs the system's support for their everyday work? 

• B. Which hardware is available for the users of the system? 

• C. What are the functional and non-functional requirements? 

• D. Who will design and implement the system? 

Actors in a use case diagram : 

• C. Represent roles of the users of the described system. 

• A. Interact with the system in the form of <<include>>-relationships. 

• B. Communicate with use cases and other actors. 

• D. Are always located within the described system.

What <b>best</b> describes when associations are used In UML modeling?

• When modeling an actor's interaction described by a use case.

• When modeling the group behavior of actors in the system.

• When modeling the behavior of use cases.

• When modeling the inheritance in a system.
