MongoDB is an open source document-oriented database system.
It is part of the NoSQL family of database systems.
Instead of storing data in rows and columns as one would with a relational database, MongoDB stores a binary form of JSON documents (BSON),
making the integration of data in certain types of applications easier and faster.
The latest MongoDB version can be downloaded from:

- MondoDB shell is now connected to mongod.exe running on the localhost interface and port 27017 by default.
At the mongo prompt, issue the following two commands to insert a record in the test collection of the default test database and then retrieve that record:
db.test.save( { a: 1 } )
db.test.find()
