Select an answer to reveal the explanation.
Short Explanation
Start with the story (who and what), then the detailed blueprint, then the built house. Conceptual → logical → physical keeps business meaning ahead of storage choices.
Full Explanation
Conceptual models capture entities and relationships in business language. Logical models add attributes, keys, and normalized structure independent of a specific DBMS. Physical models implement tables, indexes, and platform specifics. Each level answers different stakeholder questions, so sequencing conceptual then logical then physical keeps meaning ahead of storage choices.
