This means a NoSQL JSON database can store and retrieve data using literally “no SQL.” In fact, before moving on, it is important to keep in mind that NoSQL does not necessarily mean that a database does not support SQL. Instead, it means that the database is not an RDBMS . While traditional RDBMS rely on SQL syntax to store and query data, on the other hand, NoSQL database systems use other technologies and programming languages Why NoSQL? In recent times you can easily capture and access data from various sources, like Facebook, Google, etc. User’s personal information, geographic location data, user generated content, social graphs and machine logging data are some of the examples where data is increasing rapidly.
NoSQL databases often make tradeoffs by relaxing some of the ACID properties of relational databases for a more flexible data model that can scale horizontally. This makes NoSQL databases an excellent choice for high throughput, low-latency use cases that need to scale horizontally beyond the limitations of a single instance. Performance
