Exam 6: Object Modeling

For each use case, you develop a use case ____________________ in the form of a table that documents the name of the use case, the actor, a description of the use case, and so forth.

____ describe what objects need to know about each other, how objects respond to changes in other objects, and the effects of membership in classes, superclasses, and subclasses.

A method is like a blueprint, or template, for all the objects within a class. _________________________

When you create an object relationship diagram, it will serve as a guide as you continue to develop additional diagrams and documentation.

The ____ of an object is an adjective that describes the object's current status.

In a state transition diagram, the circle to the left is the final state.

A use case description documents (among other things) ____.

As shown in the accompanying figure, objects within a class can be grouped into ____, which are more specific categories within a class.

A class can belong to a more general category called a subclass. _________________________

What do relationships enable objects to do? What is the strongest kind of relationship? Walk through an example that demonstrates your understanding of the concept.

Systems analysts rely on ____________________ tools to speed up the process of creating object models and provide an overall framework for documenting the system components.

Just as objects are similar to adjectives, attributes resemble verbs that describe what and how an object does something.

MATCHING Identify the letter of the choice that best matches the phrase or definition. -After you identify this, you place the use cases on the diagram, add the actors, and show the relationships.

Unlike a DFD, a class diagram is a logical model, which evolves into a physical model and finally becomes a functioning information system.

The number of ____ needed to describe an object depends on the business requirements of the information system and its users.

____ is a widely used method of visualizing and documenting an information system.

____ are characteristics that describe the object.

If you do not use a CASE-generated model, it is not necessary that a diagram or object definition be supported by documentation.

MATCHING Identify the letter of the choice that best matches the phrase or definition. -In this, reading from left to right, the lines show direction and describe the action or event that causes a transition from one state to another.
