MongoDB (from "hu mongo us") is an open source document-oriented database system developed and supported by 10gen . It is part of the NoSQL family of database systems. Instead of storing data in tables as is done in a "classical" relational database , MongoDB stores structured data as JSON -like documents with dynamic schemas (MongoDB calls the format BSON ), making the integration of data in certain types of applications easier and faster. 10gen began Development of MongoDB in October 2007. The database is used by MTV Networks , [ 1 ] Craigslist , [ 2 ] Foursquare [ 3 ] and UIDAI Aadhaar [ citation needed ] . MongoDB is the most popular NoSQL database management system. [ 4 ]

[ 1 ] It is a NoSQL database that uses JSON to store data, JavaScript as its query language using MapReduce and HTTP for an API . [ 1 ] One of its distinguishing features is easy replication. CouchDB was first released in 2005 and later became an Apache project in 2008. Unlike in a relational database , CouchDB does not store data and relationships in tables.mysql
