Image via Wikipedia Data mining is really just the next step in the process of analyzing data. Instead of getting queries on standard or user-specified relations, data mining goes a step farther by finding meaningful relationships in data. Relationships that were thought to have not existed, or ones that give a more insightful view of the data. For example, a computer-generated graph may not give the user any insight, however data mining can find trends in the same data that shows the user more precisely what is going on. Using trends that the end-user would have never thought to query the computer about. Without adding any more data, data mining gives a huge increase in the value added by the database. It allows both technical and non-technical users get better answer, allowing them to make a much more informed decision, saving their companies millions of dollars.
