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.

The 10 Best Lines From the Apple-Samsung Trial !


After three weeks of testimony, the federal trial in San Jose pitting Apple (AAPL) and its iPhones and iPads against Samsung (SSNLF) and its Android phones and tablets has gone to the jury. It may prove to be just another battle in the endless war over mobile technology property rights, but the trial did churn out some memorable quotes. In no particular order:
“Since it is too similar to Apple, make it noticeably different starting with the front side.”
Internal e-mail citing notes from Samsung’s senior designer out of a meeting with Google officials, who requested changes in Samsung’s devices.
“In addition to my formal analysis, I had the experience of being confused.”
—Apple witness Susan Kare, who designed the “happy Mac” icon, testifying that she confused a Samsung phone for an iPhone at a pretrial meeting.
“Wouldn’t you agree that by the time the consumer turns on the phone, and goes through the steps we looked at, seeing the Samsung sign prominently for several seconds, that the consumer knows it’s a Samsung phone?”

—Samsung attorney cross-examining Kare.
“Yet when our UX is compared to the unexpected competitor Apple’s iPhone, the difference is truly that of Heaven and Earth.”
—The “crisis of design” memo written in February 2010 by Samsung executive J.K. Shin, cited by Apple as proof the iPhone helped shape Samsung’s design. Samsung said it was intended for motivational purposes.
“My recollection was that the breast feeding had to come to a stop.”
—Samsung designer Jeeyuen Wang, describing how she slept two to three hours a night while working on the Galaxy S phone, and the effect of spending so much time away from her newborn child.
“I mean, come on: 75 pages! 75 pages! You want me to do an order on 75 pages, [and] unless you’re smoking crack, you know these witnesses aren’t going to be called when you have less than four hours.”
—Judge Lucy Koh responding to an Apple lawyer’s request for a late crush of witnesses.
“It is inconceivable that Mr. Jobs, CEO of Apple during a portion of the relevant time period and inventor of the ’949, ’678, D’087, D’677, D’270, D’889, D’757, and D’678 patents, actually had so few e-mails on issues in this case and none between August 2010 and April 2011.”
—Samsung, arguing to the judge that Apple was withholding e-mail evidence it requested.
“The kids refer to it as the bellybutton. It’s an innie.”

—A Samsung lawyer’s suggested name for the iPhone home button. Apple Senior Vice President Phil Schiller testified he had not heard that before.
“The content is jittering spasmodically.”
—Apple expert witness Karan Singh, describing on-screen tablet behavior that Singh claimed shows patent infringement.
“I need everyone to stay conscious during the reading of the jury instructions, including myself. … We’re going to periodically stand up, just to make sure we’re all alive.”
—Judge Koh before reading 109 pages of legal instructions to the jury.
