The document discusses MongoDB Connector for Business Intelligence. It allows connecting MongoDB to BI tools via a SQL interface. It includes the MongoSQLD proxy daemon that translates SQL queries to MongoDB queries. It also includes MongoDRDL for generating schemas to map MongoDB data to relational tables. The connector supports authentication, security, and performance optimizations like query push-downs.
