Data mining - Essay Example t generally apply: every application must deliver benefits to the users; users must feel comfortable with the way in which the system manipulates and presents information. Data mining is based on statistical analysis and modeling techniques, Data mining becomes a strategic weapon of organizations because it increases significantly the volume of information that can be stored and the ease with which it can be updated. This enables new services to be provided in a way that was not economically feasible before. The three main steps in data mining are discovering, predicting modeling and forensic analysis. ââ¬Å"Discovery is the process of looking in a database to find hidden patterns without a predetermined idea or hypothesis about what the patterns may beâ⬠(Pushpa 2007, p.1). Discovery consists of three subcategories: conditional logic, affinities and associations, trends and associations. ââ¬Å"In predictive modeling patterns discovered from the database are used to predict the future.â⬠(Pushpa 2007, p. 2).
