Question

In system development, what is usually navigated from the superior to the subordinate class in a superior/subordinate relationship?

a) Class hierarchy
b) System structure
c) Functional division
d) Hierarchical organization

Answer 1

In system development, the class hierarchy is used to navigate from superior to subordinate classes, denoting inheritance of attributes and methods.

Step-by-step explanation:

In system development, navigation is typically from the superior class to the subordinate class in what is known as a class hierarchy. This implies that the superior class, or the more general class, contains shared attributes or methods that are inherited by the subordinate class, which is more specific. In contrast with the hierarchical organization of bureaucracy as exemplified by a company structure where an employee reports up a chain of command, in a class hierarchy of system development, the subclass inherits from the superclass, which creates an is-a relationship, indicating that the subclass is a special form of the superclass.

Answer 2

In system development, navigation typically occurs from the superior to the subordinate class in a 'class hierarchy', where the parent class serves as a basis for the subclass to inherit properties.

Step-by-step explanation:

In system development, navigation usually occurs from the superior to the subordinate class in a class hierarchy. A class hierarchy is a way of organizing classes so that classes are derived from one another. The term implies that there is a "superclass" from which other sub-classes branch off. This model is somewhat analogous to natural systems such as the taxonomic classification system used in biology, where the hierarchy moves from more general to more specific categories. Just as a shift manager at Walmart would report to a store manager, in a class hierarchy, a subclass or subordinate class inherits properties and behaviors from the superior or parent class.
