Exam 14: Object-Oriented Data Modeling

When an operation may apply to two or more classes in different ways, this is known as polymorphism.

The most common multiplicities are 0,1, *, and 1.

A graph of instances that are compatible within a class diagram is called a(n):

A destructor operation creates a new instance of a class.

A deprived attribute, role, or association is one that can be computed from other attributes, roles, or associations.

The process of replacing a method inherited from a superclass by a more specific implementation of that method in a subclass is called underwriting.

Overriding is the process of replacing a method inherited from a superclass by a more specific implementation of that method in a subclass.

In the figure below, which of the following is true?

A class-scope operation applies to a class rather than an object instance.

Encapsulation is the technique of hiding the internal implementation details of an object from its external view.

Which of the following operations does NOT alter the state of an object?

An association that has its own attributes or operations or that participates in relationships with other classes is called an association class.

An aggregation expresses a part-of relationship between a component object and an aggregate object.

The end of an association where it connects to a class is called a(n):

A(n) ________ encompasses an object's properties and the values of those properties.

The object-oriented systems development cycle consists of:

A constructor operation does not alter an instance of a class.

A part object that belongs to only one whole object and lives and dies with the whole object is called composting.

A(n) ________ is a named relationship between or among classes.

A ________ is the implementation of an operation.
