I hope you might have googled somewhat for Big Data. Though there are many nosql databases, but explanation for all can't be covered here.
It's all up-to the requirement according to which Bigdatabase/Nosql databases we choose.

Please refer following links for understanding what NOSQL databases are and why should we use it.
