What is data mining?
Data mining is the technique to search and mount large data volumes to look for conspiracies. Some of the intrusion detection systems use data mining techniques. Data mining relates with data matching, i.e., to process data from numerous sources. The purpose is to extract patterns or knowledge from a large amount of data not just to "mine" the data. The output of the data mining analysis is a summary of related and useful information for the one who search.
