Pt 4

A(n) _____ describes information about an object.

_____ are information that is sent to objects to tell it to execute one of its behaviors.

Analysts use _____ to show the objects that participate in a use case and the messages that pass between the objects over time for one particular use case.

When arranging actors and objects on a sequence diagram, it is nice to list them _____.

Which of the following objects would be most likely to be destroyed at some point in time in a sequence diagram?

A systems analyst draws a lifeline with an X at the end. This lifeline represents _____.

The focus in a sequence diagram is on __________________

On a sequence diagram, an object name of Students:List would indicate that _____.

The order of messages on a sequence diagram goes from ____ to _____.

When an object sends a message to itself in a sequence diagram, that is referred to as _____.

The first step in building a sequence diagram is to _____.

In a communication diagram, a(n) _____ between actors and objects is shown with an undirected line.

The acronym CRUD stands for _____.

A behavioral state machine is a dynamic model that shows the different states through which a single _____ passes through its life in response to events, along with its responses and actions.

A set of rules are used for performing the verification and validation walkthrough of behavioral models. One of the rules is: all entries in a CRUD matrix imply _________ being sent from an actor or object to another actor or object.

A set of rules are used for performing the verification and validation walkthrough of behavioral models. One of the rules is: all __________ contained in a behavioral state machine must be associated with a message being sent on a sequence and communication diagram, and it must be classified as a Create, Update, or Delete message in a CRUD matrix.

As behavioral models are developed, it is likely that the use cases and structural models will have to be modified.

Each object can both send and receive messages.

A sequence diagram can only be drawn to represent a single scenario in a use case.

Actors and objects are placed on a sequence diagram in no particular order.

It is possible for an object to create another object, resulting in the message going directly to the object, not its lifeline.

If you are interested in the time ordering of the messages in a system, you should use a communication diagram.

In a CRUD matrix, C represents Create.

When creating a CRUD matrix, you should use the letter U to represent Underline.

CRUD matrices are created by creating a matrix that lists the classes across the top and down the side.

The behavioral state diagram shows the different states that an object passes through in response to events, together with its responses and actions.

The initial state in a behavioral state diagram represents the point at which the object begins to exist.

In a behavioral state diagram, an event changes a value(s) that describes an object which in turn changes the object's state.

An activity in a behavioral state diagram represents the movement of an object from one state to another.

On a behavioral state diagram, an arrow is used to represent a transition.

Events are the triggers that cause an object to move from one state to another.

An action is an atomic, non-decomposable process that cannot be interrupted.

A guard condition is a Boolean expression, which allows a transition to occur only if a condition is satisfied.

An execution occurrence in a sequence diagram denotes when an object is sending or receiving messages.

Return messages in a sequence diagram are often shown using dashed lines with arrows labeled with the return value.

For sequence, communication, and behavioral state diagrams, a frame indicates the context of the diagram.

One of the guidelines for creating a sequence diagram is: Place the initiator of the scenario on the right of the diagram.

Only create behavioral state machine for "complex" objects
