Instead of using tables and rows as in the traditional relational databases, MongoDB makes use of collections and documents. Documents consist of key-value pairs which are the basic unit of data in MongoDB. Collections contain sets of documents and function which is the equivalent of relational database tables. MongoDB is a database which came into light around the mid-2000s.    MongoDB’s document are encoded in a JSON-like format, called BSON.BSON is a natural fit for modern object-oriented programming methodologies and is lightweight, fast, traversable .MongoDB uses BSON as a network transfer format for document. BSON at first seems BLOB-like ,but there exists an important difference : the MongoDB can reach inside BSON object ,even nested once, using doe notation . This allows MongoDB to built indexes and match object against query expression on both top-level and nested BSON ...
