The Mongo database system
The Mongo database system, MongoDB, has been in development since 2007. It has become the most widely used NoSQL database system. The name is a substring of the word humongous, suggesting that it works well with very large datasets (it has also been suggested that the name is after a character, played by the great NFL defensive tackle, Alex Karras, in the Mel Brooks movie, Blazing Saddles). The system is described as a document-oriented database.
You can download MongoDB from https://www.mongodb.com/download-center.
See the Appendix for details on installing MongoDB.
After installing MongoDB, start the database system with the mongo command, as shown in Figure 10-3. We are using the command line here. This is done using the Terminal app on a Mac, the Command Prompt on a PC, and a Shell window on a UNIX box.
