In the current digital era, technology is playing a crucial role in the evolution of various industries, and the same applies to the banking and financial sectors.

With the increasing complexity of banking and financial sectors, traditional approaches have been replaced by advanced models that are more suitable for financial services. Also, they provide efficient solutions, especially in terms of identifying risky business opportunities.

Apart from assisting banks in their day-to-day activities, big data analytics can also be effectively applied in the long term. Today, practically every bank uses predictive models to make critical business decisions.
