Mongo DB (from "humongous") is a cross-platform document-oriented database system. Classified as a NoSQL database, Mongo DB eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas (Mongo DB calls the format BSON), making the integration of data in certain types of applications easier and faster.

 

It has been written in C++ as a document-oriented database, so it manages collections of JSON-like documents.

Mongo DB supports cross-platform support (Windows, Linux, Solaris). It also has a rich set of data types (supports dates, regular expressions, code, and binary data).

 

Mongo DB uses memory mapped files. For Windows the data size is limited to 2GB on 32-bit machines (64-bit systems have a much larger data size).
