Design Phase
 

• What does a use case diagram represent?

  • A set of actions

  • Time sequence of statements executed

  • How to use a particular module

  • Dont know

 

• In a use case diagram, relationships between different actors are normally shown

  • True

  • False

 

• Generalization relationship exists between two use cases when

  •   A use case derives from a base use case

  • A use case derives from a base use case and specializes some of its inherited functionality

  • None

 

• Domain Object Model is used to

  • Build concept

  • Build the databases

  • Construct the logical operations

 

• Classes contain the same type objects – here the same type means

  • Coming from the same sources

  • They are of same data type

  • They are using the same attributes and methods

 

• List of potential objects can be made from a narrative problem statement by marking the

  • Verbs from the problem statement

  • Adjective from the problem statement

  • Nouns from the problem statement

  • None of the above

 

• All the potential objects we get by using noun method must be into the scope of solution space

  • True

  • False

 

10. Which tool is use for structured designing?

• Program flowchart

• Structure chart

• Data-flow diagram

• Module
