Difficulty: Easy
Correct Answer: Instance entity
Explanation:
Introduction / Context:Some designs explicitly model templates and their real occurrences. Distinguishing the instance from the template clarifies how data is populated and referenced.
Given Data / Assumptions:
Concept / Approach:In the archetype/instance pattern, the archetype holds the generalized definition, while the instance represents the specific, real-world occurrence based on that definition.
Step-by-Step Solution:
Identify “occurrence of a generalized entity” as the instance.Map to terminology: archetype = template, instance = occurrence.Select “Instance entity.”Verification / Alternative check:Examples: ContractType (archetype) vs. Contract (instance); ItemModel (archetype) vs. ItemSerial (instance).
Why Other Options Are Wrong:
Common Pitfalls:Interchanging subtype with instance. A subtype is still a template-level specialization, whereas an instance is a concrete occurrence.
Final Answer:Instance entity
