In Data Mining, you like to see hidden/unknown pattern in Datasets.
Let me ilustrate with a purchasing pattern discovered in a major drug store chain.
1-Pattern: "from 9pm to 6am 90% of people buying baby diapers also buy beer"
2-Root cause of the pattern: "husbands are the ones buying baby diapers at night so they take advantage of the trip to the drug store to by beer for themselves"
3-Business action: "Put beer close to the baby diapers"
There is no question business could have asked to find that.
Here is how it works...
1- Data mining shows the pattern a.k.a. correlation in between sales of two products in a specific timeframe.
2- Business investigates to find the rationale behind the pattern.
3- Business takes action to take advantage of the pattern - provided pattern is potentialy positive.
Hope this helps.
