Which database does Facebook & Google use ?

-
Facebook has moved to a NoSQL database named HBase. Google uses their own system called BigTable. What is NoSQL ? NoSQL is a term used to designate databases which differ from classic relational databases. NoSQL database management systems are useful when working with a huge quantity of data when the data's nature does not require a relational model. The data can be structured, but NoSQL is used when what really matters is the ability to store and retrieve great quantities of data, not the relationships between the elements.

With 73 lakh offer, this IIT Kanpur student sets a record for campus placement !

-


Agra: Agra's Karan Narain, pursuing M. Tech (final year) in computer science from IIT Kanpur, has set a new record in campus placement. He has been picked up by US company Pocket Gems for an annual package of $137,000 (over Rs.73 lakh).

This is the highest package offered to a Kanpur IITian and one of the highest in India so far.

"Pocket Gems is into mobile application development for Android and iOS. The interviews held in Kanpur were completely technical," Narain told IANS.
"I had some background in Android which could have appealed to them. It's a start-up, so has only around 100 employees. They've visited all the IITs and recruited a few students from each," he added.

Narain attributed his success to his schooling in Chennai, Hyderabad, New Delhi and Agra. "All schools are different and gave me a new experience and changed my world view for the better," he said.
