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.
