For retailers, it is crucial to anticipate what customers want since the entire product development journey is dependent on their demands. In order to make correct predictions, it is necessary to track every single step of the customer’s journeyand understand each customer individually. This tedious task is made simple by data science.

Using flexible databases like MongoDB Enterprise is one incredible way in which retailers have adopted big data analytics. It is a very useful tool for building rich customer profiles, leading to better personalization of products and services offered. Simplified omni-channel retail is yet another plus point of MongoDB big data analytics. With real-time decision making, enhanced customer engagement, and seamless customer experience, data analytics have redefined the way retail chains function.


Fighting against banking fraud is one of the most important applications of big data analytics. It can identify potentially illegal customer behavior, allowing bankers to intervene before any financial damage occurs. It is also used to detect irregularities while auditing.

Virtual Assistants powered by predictive analytics combined with natural language processing arealso being used increasingly to enable customers to view transaction histories and information about bills due.
