Hello karthik M,
No SQL is term use to designate from classic relational databases. In nosql the concept of relational database has been diluted and anew concept of key value pair has been introduced.
I am feeling great to share with you that, with the release of SQL Server 2012 Microsoft has introduced their new product called as "PloyBase"
PolyBase is a fundamental breakthrough in data processing used in SQL Server 2012
It uses the MPP algorithm to process data between Hadoop and SQL Server.
For more information about this you can contact me.
