Which of the following is NOT a valid technique to return data from an input message?

A return condition name

Which of the following is an example of an interaction diagram? b Data access diagram

Communication diagram

What is the least cohesive approach in creating use case controllers in a system?

Define a single controller for all use cases.

Which of the following is NOT a component of the design pattern template?

Description of when the pattern does not apply

True or False : Design class diagrams and interaction diagrams should be developed independent of each other.

False

True or False: Dependency relationships cannot exist between classes within packages.

False

True or False: Design class diagrams and interaction diagrams should be developed independent of each other.

False

True or False: Since updating a design class diagram is done after the use case realization is complete, visibility information is no longer necessary.

False

True or False: The activation lifeline is depicted by a vertical dashed line under an object.

False

True or False: The controller object is usually part of view layer.

False

True or False: The first-cut sequence diagram contains view layer and business layer.

False

True or False: The perfect memory assumption means that there is always adequate memory to execute the program.

False

True or False: There are two preferred methods to accessing the database. One is to have newly instantiated object call the data access object. The other is to let the controller access the data access object.

False

Which design model provides information for a design class diagram?

Interaction diagram

The customer relationship system needs to instantiate a new customer object. How should this be done?

Let the controller object do it.

Which of the following symbols is used in a communication diagram, but not in a sequence diagram?

Link

The following notation "anOrd:Order" can be interpreted as follows:

Order is an object. anOrd is the reference to that object

____ diagrams partition a design class diagram into related functions.

Package

24 What is the first step in constructing a first-cut sequence diagram from the elements of the system sequence diagram (SSD)?

Replace the :System object with all the objects that must collaborate

Given the following code, identify the pattern. Class MyBuilder { static MyBuilder builder = null; { if builder == null {builder = new MyBuilder( ); return builder; }

Singleton Pattern

True or False: A loop or repeating message or messages in a sequence diagram is depicted by a rectangle box.

True

True or False: Adding a use case controller to a sequence diagram is an example of applying a design pattern.

True

True or False: The best technique for accessing the database when multiple objects are needed is just to let the data access object instantiate objects.

True

True or False: The perfect solution assumption means that we do not worry about exception conditions.

True

True or False: The perfect technology assumption means not to worry about issues such as user security.

True

True or False: The starting point for the detailed design of a use case is always the SSD.

True
