Data Mining is the process of extracting and refining useful knowledge from large databases. The extracted information can be used to form a prediction or classification model, identify trends and associations, refine an existing model or provide a summary of the databases being mined. A number of Data Mining techniques e.g. rule induction, neural networks and conceptual clustering have been developed and used individually in domains ranging from space data analysis to financial analysis. Frequently, a single data mining technique is insufficient for extracting knowledge from a data set. Instead several techniques must be employed cooperatively to support a single data mining application
