All versions of MongoDB - a scalable, high-performance, open source, document-oriented database.
MongoDB is a widely used, general-purpose, document-oriented NoSQL database with features including high-availability replication and auto-sharding for horizontal scaling. The MongoDB database server and tools, written in C++, are open-sourced and available under AGPL v3.0 license or a Commercial License. MongoDB has strong support for dynamic querying and aggregating data including MapReduce and an Aggregation Framework. MongoDB uses BSON (Binary JSON) format for storage purposes and the MongoDB Wire Protocol for communication between client drivers and the MongoDB server. Officially supported Drivers and Client Libraries are available for most popular programming languages, and there are also Community Supported Drivers which offer alternative implementations and support for further programming languages.

The mongodb-user mailing list is very busy and almost every question on earth has been asked on there, so try searching the archives. Tip: searching Google with
" site:groups.google.com/group/mongodb-user" added to your search terms generally works better than using the Google Groups search bar.
For help with data modeling (schema design), check out the Data Modeling Considerations for MongoDB Applications documentation page or search the mailing list archives.
