Question 59

The horizontal axis on a sequence diagram is a timeline.

Question 60

Question 61

A collaboration diagram is a dynamic diagram that focuses on the organization of objects that must cooperate, by exchanging messages, to satisfy a certain behavior.

Question 62

As a dynamic model, a collaboration diagram represents the relationship among classes, but not objects.

Question 63

The relationships in the collaboration diagram relate to the exchange of messages among objects.

Question 64

The worst way to arrive at a collaboration diagram is to start from a sequence diagram.

Question 65

If you cannot describe the goal, you cannot create a satisfactory collaboration diagram.

Question 66

A statechart diagram represents milestones in the lifetime of an object when its state is stable.

Question 67

A statechart diagram is composed of the states of an object and the flow of events that change its state.

Question 68

An activity diagram provides the logical flow of activities.

Question 69

Sequence diagrams may be used at any stage of development to help you visualize the sequence of events, messages, and object responsibilities.

Question 70

Parameters are the types of data that an object requires to perform a certain task.

Question 71

Conceptual modeling usually ignores how operations are implemented.

Question 72

Attributes of objects, usually private, are exposed to the outside world through accessor operations.

Question 73

A sequence diagram is composed of a timeline, objects that interact across this timeline, and the messages that they exchange.

Question 74

Each column in the sequence diagram identifies an instance of an actor or a class. Each "row" is the message sent or received by the entities in the column.

Question 75

The main value of a statechart diagram is that it presents a clear picture of what an object expects from another.

Question 76

The collaboration diagram is the only dynamic model that illustrates the milestones in the lifetime of one class of objects in its entirety.
