It also highlights the use of advanced statistics and computer science to measure, mitigate and manage various risks associated with banks' business with its customers and other banks. In addition, the book reveals the growing influence of customer relationship management and data mining in tackling various marketing-related problems and fraud detection problems in the banking industry.
