MongoDB

From Wikipedia

MongoDB (from "humongous") is a cross-platform document-oriented database system. Classified as a "NoSQL" database, MongoDB eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas (MongoDB calls the format BSON), making the integration of data in certain types of applications easier and faster.
