Entry Certificate in Business Analysis (ECBA) — Question 9
What is a logical data model used for?
Answer options
- A. Abstracting a 'conceptual data model' to incorporate the rules of normalization to manage data integrity and relationships.
- B. Abstracting a 'physical data model' to describe the physical organization of data and its relationships within a database.
- C. Defining the logical rules that govern decisions in an organization and that define, constrain, or enable organizational operations.
- D. Defining a solution independent view of how a business perceives its information without applying any constraints.
Correct answer: A
Explanation
The correct answer, A, is accurate because a logical data model focuses on organizing data and ensuring data integrity through normalization. Options B and D discuss physical organization and a solution-independent view, respectively, which do not pertain to the logical data model's purpose. Option C refers to organizational decision rules rather than data management.
