A database analyst is modelling a database for a large toy manufacturer. Which statement describes a logical database model?

Show Suggested Answer Hide Answer
Suggested Answer: C

A logical database model is a data model of a specific problem domain expressed independently of a particular database management product or storage technology. It describes data using notation that corresponds to a data organization used by a database management system, such as relational tables and columns. It also includes rules of normalization, which are the process of converting complex data structures into simple, stable data structures12 Reference: 1: Logical schema - Wikipedia 2: What Is a Data Model? | Coursera

I thought logical models were more about the relationships and constraints, so I’m thinking it could be A, but I need to double-check my notes.

I feel like the logical model should include normalization rules, which makes me lean towards C, but I could be mixing it up with something else.

I remember practicing a question similar to this, and I think the answer might be B, but I'm not entirely sure.

I think a logical database model is more about how data is structured rather than the physical design, so maybe it's C?
