Unfortunately, the relational databases have very poor features
to quickly adopt new types of data because of its rigid and
static schema based approach, and is not suitable for semistructured
and unstructured data.
Finally, the NoSQL meets the growing trends of storage,
processing and retrieval of data by providing a flexible,
schema-less data model that maps the organization’s
requirement and simplifies the communication between the
application and database, that results in less writing code,
debugging and maintenance becomes more easier.
