The amount of data collected by businesses today is phenomenal. The analysis of this data is critical as more and more businesses are using this data to analyze their competition, product or market. Data mining is the process of digging through this mass of data to discover information (patterns or new knowledge) that can be critical to decision making in organizations. Data mining has added importance as organizations begin to rely more heavily on this information to make critical decisions. The need for using the right data mining tools effectively to support decision making cannot be overemphasized.
