This document discusses how insurance companies use MongoDB. It provides examples of how MongoDB allows insurance companies to create a single customer view, consolidate data from multiple disparate systems, and distribute claims information globally in real-time. MongoDB provides a flexible schema, automatic replication of data, and the ability to query data locally for improved customer experience, risk analysis, fraud detection, and claims processing. The document highlights several insurance companies that have adopted MongoDB to unify customer data, modernize legacy systems, and power new data-driven applications and services.
