What is NoSQL?
NoSQL stands for “non-SQL” or “Not only SQL” and is pronounced “no sequel”. It refers to a class of databases that accomplish specialized tasks at a scale that can not be served by traditional relational database management systems (RDBMS). NoSQL systems often require custom development in Java, Python and a wide variety of other programming languages and tools. NoSQL (non-SQL) database systems often also provide developers with SQL-like tools and APIs to access and exploit the specialized functions of the system.
NoSQL systems can scale horizontally across many (hundreds or thousands) servers or nodes and can scale to many terabytes or even petabytes of data. These databases are a great fit for mobile, web and gaming applications because they are flexible, scalable, high performing and highly functional.
NoSQL (non-SQL) database systems simplifies the programming as developers no longer have to account for inconsistent data scenarios.
