A very popular open source NoSQL database from MongoDB, Inc. (www.mongodb.com) that runs under Windows, Mac, Linux and Solaris on Intel, ARM, POWER8 and System z hardware. MongoDB uses a document data model rather than relational tables and was developed in 2007 by 10gen (name changed to MongoDB in 2013). The MongoDB data file is a document formatted in BSON, a binary version of JSON with additional data types. Touted as "developer friendly," MongoDB can be accessed in any programming language unlike object databases that are tied to one object-oriented language. MongoDB customers are able to manage gigantic databases, because it scales across many servers with automatic failover. Paid subscriptions provide tools for advanced management and security as well as tech support. The company also offers MongoDB Atlas, a hosted service. See JSON, NoSQL and MEAN.
