Certified Data Management Professional – Fundamentals (CDMP) — Question 16

In a data model, domains can be used for:

Answer options

• A. Reducing the amount of coding required in the database
• B. Public viewing of the data model
• C. Consolidation of data into subject areas
• D. Consistency and standardization of data values
• E. Separating concepts into business ideas

Correct answer: D

Explanation

The correct answer is D because domains are designed to ensure consistency and standardization of data values across the database. Options A, B, C, and E do not accurately describe the primary function of domains, which is focused on maintaining uniform data values rather than coding efficiency, public access, data grouping, or business concept separation.
