large amount of data stored in data warehouses are often used for data mining. the data is first cleansed to remove duplicate data and errors. The data is then analysed using a tool such as artifiacl intelligen. An analysing report is then analysed by an analyst who decides if the parameters need to be refined, other data analysis tools need to be uesd or if the results need to be discarded because the are unsusable. the analyst passes the final result to the decision makers who decide on the appropriate action.
