When naming a subtype entity in a supertype/subtype model, which naming guidance should be followed?

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:

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
