MongoDB is a schema-free, document-oriented database written in the C++ programming language. It manages collections of BSON documents that can be nested in complex hierarchies and still be easy to query and index, which allows many applications to store data in a natural way that matches their native data types and structures.
The software includes the following features:
- Document-oriented storage: JSON-style documents with dynamic schemas offer simplicity and power.
- Full Index Support: Index on any attribute, just like you’re used to.
- Replication & High Availability. Mirror across LANs and WANs for scale and peace of mind.
- Auto-Sharding. Scale horizontally without compromising functionality.
- Querying. Rich, document-based queries.
- Fast In-Place Updates. Atomic modifiers for contention-free performance.
- Map/Reduce. Flexible aggregation and data processing.
- GridFS. Store files of any size without complicating your stack.
- Commercial Support. Enterprise class support, training, and consulting available.
