It has proven adept in storage and retrieval of various data structure types, whether the data is structured or not. Lacking the requirements of predefined schema, applications with NoSQL develop faster, allow modifications in real-time, and require minimal overhead. With ease of scaling, multiple industries have found widespread use.
