Question 168

Options:
A.
No discipline at all
B.
Less discipline than relational data management
C.
More discipline than relational data management
D.
Big ideas with big budgets
E.
A certification in data science
Answer:
C
Explanation:
Big data management involves handling large, complex, and unstructured datasets, requiring greater discipline in governance, quality, and processing compared to relational data. The DAMA-DMBOK states: “Big data management requires more discipline than traditional relational data management due to the volume, velocity, variety, and veracity challenges” (DMBOK2, Chapter 13: Data Integration and Interoperability, p. 521).
Options A, B, D, and E are incorrect: big data requires discipline, not less or none, and budgets or certifications are irrelevant to the question.
