Following a reorganization of a company's legacy database,
it was discovered that records were accidentally deleted.
Which of the following controls would have MOST effectively
detected this occurrence?
A. Range check
B. Table lookups
C. Run-to-run totals
D. One-for-one checking
Answer / guest
Answer: C
Run-to-run totals would have been an effective detective
control over processing in this situation. Table lookups and
range checks are used for data validation before input, or
as close to the point of origination as possible.
One-for-one checking is time consuming and therefore less
effective.
