A large number of companies have found that the relational database model that have been predominant since the late seventies insufficient. It might be that the complex logics of an RDBMS is too much overhead for their storage needs, when all they really need is to store objects with specific ids. It could be because of the need to store huge amounts of data and therefore needing to partition the data across multiple servers. It could also be that they need to model complicated domains where relational databases would end up with an explosion of tables, and joins would kill performance.

NOSQL is not one silver bullet, it is a large number of different databases that take different approaches to data storage to solve the aforementioned problems, the only common denominator is that none of them are relational databases. This session will give an overview of the space of NOSQL databases and what they can do for you.
