It can achieve this through the use of MongoDB is used by some of the largest companies in the world, including Facebook, Google, Nokia, MTV Networks, Cisco, Forbes, and many more.MongoDB is also a cross platform DBMS, currently supporting Windows, Mac, Solaris, and various Linux distributions at the time of writing.A MongoDB database is different to a relational database in that, MongoDB uses a In MongoDB, a collection is a group of documents.
