This document discusses how retail banks can use MongoDB to address key challenges:
1) Changing regulations require agile systems that can adapt quickly.
2) Synchronizing global customer data in real-time is difficult due to latency issues.
3) Providing a 360-degree view of customers across channels is a challenge with siloed systems.
The case study describes how Infusion and MongoDB helped MetLife build a single customer view application in 90 days that aggregated data from 70 systems, providing a more holistic customer experience. This project demonstrated how acting like a startup can help large companies move faster.
