MongoDB
MongoDB is a high-performance, open source, schema-free
document-oriented data store that is easy to deploy, manage
and use. This network accessible software is written in C++. As the
database is document-oriented it manages collections of JSON-like
documents. Many applications can therefore model data in a more natural
way, as data can be nested in complex
hierarchies and still be query-able and indexable.
MongoDB consists of mongod, the database process, mongos, a
sharding
controller, and mongo (the database shell which uses interactive
Javascript). The shell is extremely versatile letting developers view,
insert, remove, and update data in their databases, as well as obtain
replication information, setting up sharding, shut down servers,
execute JavaScript, and much more.
High performance, scalability, and reasonable depth of
functionality are the goals for the project. It is used in many
different prouduction environments including Craigslist, SourceForge,
The New York Times, Intuit, Business Insider, github, SecondMarket and
others.
A number of graphical user interfaces have been created by independent
developers. Examples include Mongo3, Fang of Mongo, RockMongo, and Opricot.
