Validity (Right Answer)
Security
Integrity
None of above

The automated, prospective analyses offered by data mining move beyond the analyses of past events provided by _____________ tools typical of decision support systems.
Introspective
Intuitive
Reminiscent
Retrospective (Right Answer)

The technique that is used to perform these feats in data mining is called modeling, and this act of model building is something that people have been doing for a long time, certainly before the _________ of computers or data mining technology.
