NoSQL database, also called Not Only SQL, is
an approach to data management and database design that's useful for very large
sets of distributed data. NoSQL, which encompasses a wide range of
technologies and architectures, seeks to solve the scalability and big data performance issues
that relational databases weren’t designed to
address. NoSQL is especially useful when an enterprise needs to access and
analyze massive amounts of unstructured data or data that's
stored remotely on multiple virtual servers in the cloud.
