Why NOSQL ??(Not Only SQL or Non-relational databases)

{“author”: “Shivam Singhal”, “organization”: “Atlogys Pvt. Ltd.”}

NOSQL attempts to address dynamic : Developers are working with applications that create massive volumes of new, rapidly changing data types — structured, semi-structured, unstructured and polymorphic data.

Flexible(Agile Model): Long gone is the twelve-to-eighteen month waterfall model. Now small teams work in agile sprints, iterating quickly & pushing code every week or two, some even multiple times a day.

Scalability: 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.

Availability: 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.
