Data mining automates the detection of relevant patterns in a database, using defined approaches and algorithms to look into current and historical data that can then be analyzed to predict future trends. Because data mining tools predict future trends and behaviors by reading through databases for hidden patterns, they allow organizations to make proactive, knowledge- driven decisions and answer questions that were previously too time-consuming to resolve.

Most data mining tools can be classified into one of three categories: Traditional data mining tools Dashboards data mining tools Text-mining tools.
