NoSQL =

Non-relational next generation operation data stores and databases

no joins +

light transactional semantics =

horizontally scalable architectures

NoSQL =

Non-relational next generation operation data stores and databases

Benefits :

- scale

- leverage the vast swathes of semi-structured data

- agility, nimbleness
