See the future with the help of Data Mining

What is data mining ?

Data mining is a process in which we extract some useful information from dataware house, process that data, find some pattern in that data, to assimilate it.

I'll try to give the most simple example of data mining, Actually we already did the data mining thing in our college and school days, and most of the engineers has clear there examination because of data mining.

Well, remember in our final examination day, when we don't have the time to study all the topics in detail what we do ?

We do data mining. First we collect all the question paper of last five or six years. then we select the questions which has been repeated more frequently ( in my case, i prefer at least more than 3 times). than in that selected question, we process it and try to analyze it. and than after analysis we try to find out patterns in that selected question, like which type of question has been repeated more time and it is coming from which section. after seeing all the patterns, we conclude that, which topic is more important, and in which topic examiner is more interested.

In same manner most of the business entities try to find out there answers to question like :
"Which clients are most likely to respond to my next promotional mailing, and why?"
