Databases -Relational and Non relational

Hi Guys,

We have worked on relational database (oracle , sql server , mysql , teradata) .So with the coming of hadoop into picture i started analysis no relational databases.Non relatonal databases are used for storin unstructured data . Like your windows file system c drive , d drive and all

We can store email in our database stables but then our databases table will serve as file systems .

I will write more on this topic as i get time.
