- 15. Data Mining • Data mining, “the extraction of hidden predictive information from large databases”. • It is a powerful new technology with great potential to help companies focus on the most important information in their data warehouses. • The main focus of data mining process is to obtain information from the data and converted it into an knowledgeable and reasonable structure for further use. 09/04/18 15 09/06/18 15
