Exam 18: Object-Oriented Design and Modeling Using the UML

One advantage of using design patterns is that they provide designers with a short-hand notation for discussing design issues.

Public attributes can be accessed and public methods can be invoked by any other method in any other class.

An object framework is a set of related, interacting objects that provide a well-defined set of services for accomplishing a task.

Attributes and methods that are visible from any method in any class are said to be:

This is a popular tool for documenting the behaviors and collaborations for an object.

Controller classes implement the business logic or business rules of the system.

Method is the software logic that is executed in response to a message.

By employing persistence classes, it allows the entity classes to be more implementation specific and potentially more usable.

Attributes and methods that are visible from any method in the class in which the attribute or method is defined are said to be:

_________________________________ diagrams model the life cycle of a single object.

_________________ classes isolate the other objects from operating system-specific functionality.

Navigability is illustrated with an arrowhead pointing only to the direction a message can be sent.

__________________________ classes are identified during systems analysis and usually correspond to items in real life and contain information, known as attributes, that describes the different instances of the entity.

An approach used to specify the software solution in terms of collaborating objects, their attributes and their methods is called object oriented design.

In which of the following are the use case scenarios acted out by the participants, where participants may assume the role of actors or object types that collaborate to process a hypothetical business event?

_____________________________ classes are those that hold application or business rule logic.

A component is a group of objects packaged together into one unit. An example of a component is a dynamic link library (DLL) or executable file.

________________________________ is the software logic that is executed in response to a message.

Name four types of object classes that are introduced as a result of implementation decisions that were made during systems design: ___________________.

GOF creational patterns provide guidance for designing classes to instantiate new objects.
