It is obvious that big data can assist banks in better understanding their clients, among other things. Applying such insights to marketing efforts ensures that they are better focused and, as a result, poised to provide greater outcomes.
Personalized marketing, which targets customers based on an analysis of their unique buying habits, also uses Big Data. Financial services organisations can use sentiment analysis to gather data from customers’ social media profiles in order to determine their demands and then construct a credit risk assessment. This can also aid in the creation of an automated, precise, and highly individualised customer service.
 By applying incentive optimization, attrition modelling, and compensation optimization, Big Data aids Human Resources management.
