Question 3

Information systems rarely include more than one class.

Answer 3

False

Question 4

We can assume the object knows how to do the __________ methods.

Question 5

The best way to begin to understand an object-oriented system is to start with a very complex example.

Question 6

A system is a collection of interacting __________.

Question 7

What assumptions can we make when using standard methods?

A) The object knows how to do the standard methods.
B) The object will not use the standard methods.
C) The object inherits the standard methods.
D) The object knows how to do the custom methods.

Question 8

The use case diagram, the scenarios, and the sequence diagrams verify and complete the details of the __________ __________.

Question 9

A(n) _________ diagram is used to model scenarios.

Question 10

The structured analysis approach uses the data flow diagram to create a logical model of the system.

Question 11

You should always examine the _________________ of the user and adjust the model to reflect the requirements.

Question 12

Standard methods are implied by the listed __________ of a class.

Question 13

The ________________ approach is used to try to understand the capabilities of the system.

Question 14

What should you always examine so that models will reflect the system requirements?

A) The knowledge of the user
B) Work context of the user
C) The knowledge of the supervisor
D) Work context of the supervisor

Question 15

Which of the following is NOT a diagram method?

A) Use case.
B) Data flow.
C) Generalization/Specialization
D) Package

Question 16

To verify that all requirements are satisfied, it is important to walk through all of the desired use cases required by the user.

Question 17

Which of the following best describes a collection of interacting objects?

A) Family
B) Community
C) Hierarchy
D) System

Question 18

A(n) __________ model of the system is represented by the data flow diagram.

Question 19

A sequence diagram is used to model __________.

Question 20

Typically class diagrams only explicitly list __________ methods.

Question 21

Each use case will only have one scenario.

Question 22

In a class diagram, no custom methods are indicated, the class is limited to standard methods.

Question 23

The object-oriented approach involves creating models that define the requirements, the design, and the implementation of a computer system.

Question 24

Use cases are identified by looking for events that might cause the user to interact with the system.

Question 25

The placement of responsibilities in the class diagram does not affect the capabilities.

Question 26

Data flow definitions are always needed.
