Data mining is the process of exploration and analysis, by automatic or semi automatic means, of large quantities of data in order to discover meaningful patterns and rules. Data Mining, also popularly known as Knowledge Discovery in Databases (KDD), refers to the nontrivial extraction of implicit, previously unknown and potentially useful information from data in databases. Data mining systems can be categorized according to the kinds of knowledge they mine based on data mining functionalities such as characterization, discrimination, association and correlation. One of the primary data mining tasks is clustering which is intended to help a user discovering and understanding the natural structure or grouping in a data set.
