Transient data is which of the following?
Answer: A
Correct answer: Data in which changes to existing records cause the previous version of the records to be eliminated
Transient data is overwritten: the new value replaces the old and the old is gone. Operational systems work this way, because they need to know the current state. A warehouse instead keeps periodic data, adding a new record and retaining the previous one, which is what makes historical analysis possible.
