NoSQL databases are non-relational, open-source, distributed, schema-less, and cluster friendly databases. They are hugely popular today owing to their ability to scale out or scale horizontally and the adeptness at dealing with a rich variety of dаta: structured, semi-structured and unstructured data. They are malleable and flexible enough to accommodate sparse datasets, besides maintaining cost efficiency and availability. Developers are working with applications that create massive volumes of new, rapidly changing data types – structured, semi-structured, unstructured and polymorphic data. Applications that once served a finite audience are now delivered as services that must be always-on, accessible from many different devices and scaled globally to millions of users. Organizations are now turning to scale-out architectures using open source software, commodity servers and cloud computing instead of large monolithic servers and storage infrastructure. Increasingly being used in big data and real-time web applications are NoSQL databases. NoSQL are the “Not only SQL” databases, implying that they support SQL-like query languages, or sit alongside SQL databases in polyglot persistent architectures.
