NoSQL databases are more scalable and provide superior performance. If the database runs on a single server, then it will reach a scaling limit. Relational Database Management System(RDBMS) i s not the correct choice when it comes to handling big data by the virtue of their design since they are not horizontally scalable. Applications are storing more and more data and are accessing it at higher rates. Modern applications are more networked, social and interactive than ever. This data is stored in a predefined data model which is not very much flexible for today’s real-world highly growing applications. SQL databases store data in tabular format. This format of storage is called BSON ( similar to JSON format). It means that MongoDB isn’t based on the table-like relational database structure but provides an altogether different mechanism for storage and retrieval of data. MongoDB, the most popular NoSQL database, is an open-source document-oriented database.
