Which of the following is not a reason that operational data are difficult to read?
Answer: A
Correct answer: Non-duplicated data
Duplicated data is a problem; non-duplicated data is what you want. The genuine difficulties with operational data are that it is dirty, that values are missing, that it is not integrated across sources, that there is too much of it, and that it may be in the wrong format or of inconsistent granularity.
