Generalization is the process of defining more general entity types from a set of more specialized entity types.

  • A.True
  • B.False

Answer: A

Correct answer: True

Generalisation runs upward: several specific entity types are examined, their common attributes and relationships are abstracted, and a supertype is created to hold them. Specialisation runs the other way, from one general type down to subtypes - the two processes arriving at the same structure from opposite directions.
