MongoDB 3.0 recently released, is an open-source, document-oriented database designed for ease of development and scaling. Think of MySQL but with JSON-like objects comprising the data model, rather than RDBMS tables. Significantly, MongoDB supports neither joins nor transactions. The key features in this latest release include support for the WiredTiger storage engine, pluggable storage engine API, SCRAM-SHA-1 authentication mechanism, and improved explain functionality. MongoDB Ops Manager, which includes Automation, Backup, and Monitoring, is now also available.
