Examples of industries that use data mining is the banking industry. There are still many banks using conventional methods in the analysis of their customers.

Data mining can help bank to create profiling customer. Results or final output obtained if the bank can execute customer relationship management is increasing customer loyalty to the bank, increasing profitability, and reducing customer acquisition costs.
