MongoDB is a high-performance, open source, schema-free
document-oriented data store that's easy to deploy, manage
and use. It's network accessible, written in C++ and offers
the following features:

* Collection oriented storage - easy storage of object-style data

* Full index support, including on inner objects

* Query profiling

* Replication and fail-over support

* Efficient storage of binary data including large objects (e.g. videos)

* Auto-sharding for cloud-level scalability

High performance, scalability, and reasonable depth of functionality
are the goals for the project.
