Question

Generalization = bottom-up design process that combines entity sets that have common features into a superclass.

e.g. {TRUCK, CAR} generalizes into VEHICLE.
TRUCK, CAR = subclasses. VEHICLE = superclass.

Options:
A. Abstraction
B. Aggregation
C. Generalization
D. Synthesis

Answer 1

Generalization is a concept in computer science where subclasses with common features are combined into a superclass, reflecting the use of inductive reasoning to form broader generalizations from specific instances.

Step-by-step explanation:

The concept in question is Generalization, which is a bottom-up design process in database design and object-oriented programming that involves creating a superclass based on the common features of lower-level subclasses. Generalization, as depicted in the provided example where {TRUCK, CAR} are subclasses that generalize into VEHICLE superclass, falls into the category of object-oriented abstraction concepts. It simplifies the design by allowing one to use a single generic entity (superclass) to represent all the entities that share common attributes and operations, while the specific variants are represented as subclasses.

Generalization is one of the several types of abstractions in computer science. Additionally, this process permits inductive reasoning, where specific instances (such as TRUCK and CAR as separate entities) lead to the formation of broader generalizations (like the VEHICLE superclass). This matches the general approach of moving from specific instances to generalities, which is a form of inductive reasoning.
