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

A(n) ________________________________________ card is a popular tool for documenting the behaviors and collaborations for an object.

In actor collaboration, the use case scenarios are acted out by the participants. The participants may assume the role of actors or object types that collaborate to process a hypothetical business event.

The process of using object-oriented techniques for designing a new system is referred to as _______________________________.

The responsibility of a(n) __________________________ class is twofold: (1) it translates the user's input into information that the system can understand and use to process the business event; (2) it takes data pertaining to a business event and translates the data for appropriate presentation to the user.

A(n) __________________________________ is a set of related, interacting objects that provide a well-defined set of services for accomplishing a task.

A(n) _____________________________ triggers the change in state when something happens or when the value of one of the attributes changes.

________________________________ classes process messages from an interface class and respond to them by sending and receiving messages from the entity classes.

If you needed to design for varying and changing policy algorithms, you could use:

What is a design pattern?

A class that handled reading and writing to a database would be an example of a(n):

An interface class is an object class that provides the means by which an actor can interface with the system.

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

Interface classes are a means through which the attributes will interface with the instances of an entity.

What diagram depicts the interaction of objects, focusing on their structural organization?

The degree to which one class is connected to or relies upon other classes is called _______________.

_________________________________ diagrams are also implementation type diagrams that describe the physical architecture of the hardware and software in the system. They depict software components, processors, and devices that make up the systems architecture.

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

The authors of the 1995 book, Design Patterns, which proposed a set of 23 patterns for OO design are known collectively as the ___________________.

GOF structural patterns provide guidance on how classes can be designed to form larger structures.

Two overarching goals of object-oriented design are high coupling and low cohesion.
