What is MongoDB?

MongoDB (from “humongous”) is a scalable, high-performance, open source, schema-free, document-oriented database. Written in C++. MongoDB bridges the gap between key-value stores (which are fast and highly scalable) and traditional RDBMS systems (which provide structured schemas and powerful queries).

MongoDB is very interesting document-oriented database, because it has really awesome features:

• Document-oriented storage (the simplicity and power of JSON-like data schemas)
• Dynamic queries
• Full index support, extending to inner-objects and embedded arrays
• Query profiling
• Fast, in-place updates
• Efficient storage of binary data large objects (e.g. photos and videos)
• Replication and fail-over support
• Auto-sharding for cloud-level scalability
• MapReduce for complex aggregation
• Commercial Support, Training, and Consulting

This guide uses EPEL-repository and Chris Lea’s Yum Repository where you can find MongoDB RPM packages (i386 and x86_64) for CentOS and Red Hat (RHEL).
