Conceptual data modeling focuses on the main business objects and how they relate to each other at a high level, without getting into storage details or specific attributes. The statement describing high-level entities and relationships without detailed attributes fits this level because it communicates the essential structure (for example, Customer and Order and the relationship between them) without listing attributes or keys. This approach supports business understanding and remains technology-agnostic. In contrast, referring to mapping to database tables and storage specifics points to implementation details, adding attributes and keys belongs to a more detailed logical model, and specifying physical storage layout and indexing is about the physical deployment. For example, a conceptual model might show Customer and Order and the relationship that a customer places an order, without listing attributes like name or order date or defining primary keys.
