Correct Answer: C
Solution :
Data mining is the process of studying trends, finding correlations and patterns among dozens of fields in large relational data bases, eg. One grocery chain used the data mining software to analyze local buying patterns, they discovered that when men bought diapers on Thursday and Saturdays, they also tended to buy beer. Further analysis showed that these shopper typically did their weekly grocery shopping on Saturdays. On Thursdays, they only bought a few items. The retailer concluded that they purchased the beer to have it available for the up-coming weekend. The grocery chain could use this newly discovered information in various ways to increase revenue, eg. They could move the beer display closer to the diaper display. And they could make sure beer and diapers were sold at full price on Thursdays.
