AA singular noun
-
BSpecific to the organization
-
CConcise
-
DAll of the above
Answer
Correct Answer: All of the above
Explanation
Introduction / Context:Clear, consistent entity names improve communication and model quality. Subtype names should convey meaning precisely yet succinctly.
Given Data / Assumptions:
- Subtype names represent specialized categories of a supertype.
- Good naming conventions aid maintainability and stakeholder understanding.
Concept / Approach:Use singular nouns (e.g., “PremiumCustomer”), tailor terminology to organizational context, and keep names concise without losing clarity. These practices apply to both supertypes and subtypes.
Step-by-Step Solution:
Evaluate each rule: singular → standard; specific → improves relevance; concise → improves readability.All guidelines apply simultaneously.Verification / Alternative check:Modeling standards and naming style guides endorse singular, concise, business-specific names.
Why Other Options Are Wrong:Picking only one rule ignores other equally important conventions.
Common Pitfalls:Overly long names or vague generic labels that confuse stakeholders.
Final Answer:All of the above
