DEFINITION


<

The Data Mining practice aims at making emerge economic optimum solutions, by the crossing of data issued from very large banks, based on pre-established criteria, and in a minimum of time :

« Data mining (DM), also called Knowledge-Discovery in Databases (KDD) or Knowledge-Discovery and Data Mining, is the process of automatically searching large volumes of data for patterns using tools such as classification, association rule mining, clustering, etc.. Data mining identifies trends within data that go beyond simple analysis. Through the use of sophisticated algorithms, users have the ability to identify key attributes of business processes and target opportunities.
Data mining is the science of extracting useful information from large data sets or databases, and has been defined as " the nontrivial extraction of implicit, previously unknown, and potentially useful information from data ".

It involves sorting through large amounts of data and picking out relevant information. These data can be stored in datawarehouse, but can also be recovered from rich sources like Internet. It is usually used by businesses and other organizations, but is increasingly used in the sciences to extract information from the enormous data sets generated by modern experimentation.
