Answer options

• A. Each data element in the source systems
• B. Unique identifiers of enterprise concepts
• C. Current data over historical data

• E. Alignment of the data dictionaries

Correct answer: B

Explanation

The correct answer is B because the data vault approach emphasizes the importance of unique identifiers for enterprise concepts to ensure consistency and traceability in data integration.
