Most operational databases can be used for many BI applications.

  • A.True
  • B.
    False

Answer: B

Correct answer: False

Operational data is generally poorly suited to BI without substantial preparation: it is dirty, has missing values, is spread across non-integrated sources, is too voluminous, and is granular in ways that do not match the analysis. That gap is exactly why data warehouses, with their extraction, cleaning and preparation programs, exist.
