Discuss IIBA CBDA Exam Topic 1 Question 53

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

AThe layer of views created to summarize data or provide another perspective of certain data

BA model that depicts the actual design of the relational database

CAn abstraction of the conceptual data model that includes rules of normalization

DModelling that involves objects being defined at the schema level

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

D sounds off. Schema level is too technical for a logical model.

A is interesting too, but it’s more about views, not the model itself.

But B is too specific. C covers more ground, I feel.

Luther 1 month ago

I’m leaning towards B. The actual design is crucial for implementation.

Josue 2 months ago

I agree, C seems right. Normalization is key in database design.

Eric 2 months ago

I think the answer is C. It makes sense to abstract the conceptual model.

Tawna 2 months ago

I feel C captures the essence of logical models best.

Isabella 2 months ago

A is interesting too, but not really a model.

Latrice 2 months ago

But B is too specific. C covers more ground.

Emeline 2 months ago

I’m leaning towards B. It describes the actual design well.

I think the answer is C. It makes sense as an abstraction.

Patria 3 months ago

Not sure about C, feels a bit too abstract for me.

Denise 3 months ago

Totally with you on C, makes the most sense!

Delpha 3 months ago

Wait, normalization? Isn't that super complicated?

Ariel 3 months ago

I thought B was right, isn't that the design part?

Miss 4 months ago

C is the correct answer, it's all about normalization!

Patti 4 months ago

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.

Georgiann 4 months ago

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.

Celestina 4 months ago

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

Tenesha 4 months ago

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