What is MongoDB?
MongoDB is an open source, document-oriented database designed with both scalability and developer agility in mind. Instead of storing your data in tables and rows as you would with a relational database, in MongoDB you store JSON-like documents with dynamic schemas.MongoDb is based on NoSQL.

NoSQL is a class of database management systems (DBMS) that do not follow all of the rules of a relational DBMS and cannot use traditional SQL to query data. 

NoSQL-based systems are typically used in very large databases, which are particularly prone to performance problems caused by the limitations of SQL and the relational model of databases. Many think of NoSQL as the modern database of choice that scales with Web requirements. 

Advantages of MongoDB over RDBMS

  • Schema less : MongoDB is document database in which one collection holds different different documents. Number of fields, content and size of the document can be differ from one document to another.
  • Structure of a single object is clear
  • No complex joins
  • Deep query-ability. MongoDB supports dynamic queries on documents using a document-based query language that's nearly as powerful as SQL
  • Tuning
  • Ease of scale-out: MongoDB is easy to scale
  • Conversion / mapping of application objects to database objects not needed
  • Uses internal memory for storing the (windowed) working set, enabling faster access of data
