The data mining can be carried with any traditional database, but since a data warehouse contains quality data, it is good to have data mining over the data warehouse system. Data Mining supports knowledge discovery by finding hidden patterns and associations, constructing analytical models, performing classification and prediction.
The data warehouse must be done before data mining. The data warehouse must have data in a wellunified pattern so that data mining could be abstract the information in a useful scheme. Data warehouse stands to the method or process of accumulating and planned information into one general database, while data mining stands to the method or process of decaying efficient information from .
