MongoDB is a document-oriented database that's highly scalable and delivers very high-performance, especially with massive data sets that need to be spread across multiple servers. It blends the things you expect with any database - like indexing, querying, and high availability - with powerful new features like easy horizontal scaling ("auto-sharding"), map/reduce aggregation, and a flexible document data model to support dynamic schemas.
MongoDB in Action is a comprehensive guide to MongoDB for application developers. The book begins by explaining what makes MongoDB unique and describing its ideal use cases. A series of tutorials designed for MongoDB mastery then leads into detailed examples for leveraging MongoDB in e-commerce, social networking, analytics, and other common applications.
