The ideal and reality of the big data of the own gold house in the "number"

As if just overnight, "big data" fire.

The legendary story of Big data, a merger case for the commanding heights of large data, one by one, the IT vendors who rotate the big data strategy, and there's a seminar on big data, and there's a new excitement, a new opportunity, and a new challenge in the IT world.

"Number" of own gold House

Strictly speaking, big data is not a new word, Bill Inmon, known as "the father of the Data Warehouse", has often hung "da data" on his lips in the late 90. The rapid popularity of big data in the last one or two years is due to the rapid development of the Internet, mobile devices, IoT of things and cloud computing, which produces huge amounts of data every second-from the advent of civilization to the 2003, when human beings create only 5 EB (5 exabytes) of data, But we now create the same amount of data in just two days. Benjamin Woo, vice president of IDC's global storage and large data research project, said global data use was expected to surge 44 times times to 35.2ZB by 2020. What is the concept of 35ZB? (1ZB=1024EB=1048576PB=1073741824TB,1073741824TBX35=37580963840TB), which means that the world probably needs 37.6 billion 1TB hard drives to store data.

But the big data is not a single exponential measure. For large data, IDC is defined as: "A new generation of architectures and technologies designed to get value from high frequency, high-capacity, different structures and types of data more economically." "People generally generalize this definition to four V, that is, greater capacity (volume, leap from TB to Petabyte, even EB-level), higher diversity (produced, including structured, semi-structured, and unstructured data), and faster generation speed (velocity). The combination of the previous three "V" drives the fourth factor-value (values).

There are many stories about the value of big data that can be corroborated:

Academics at Indiana University and Manchester University in the United Kingdom have analyzed public sentiment by extracting unstructured data from Twitter, and then contrasting the mood curve with the Dow Jones Industrial Index, finding that the market could be predicted 3-4 days ahead. For this, they have launched Europe's first social-media-based hedge fund.

(in millions of United States dollars)

British scientists, for example, are tracking the outbreak of flu based on Twitter data. They are based primarily on the user's key words in the message, such as "My headache", and combined with the site of the user's release, according to the regional and British Ministry of Health official data comparison, finally set up a forecast model. The entrepreneurial team "Sickweather" even launched its own entrepreneurial program on the theme of disease prediction.

There are a lot of big data cases like this, and the whole business community has a very high opinion of the impact of big data-

Making full use of large data can help global personal positioning service providers add $100 billion trillion in revenue and help Europe's public sector manage to raise the value of $250 billion a year, the McKinsey Global Research Institute said in a May 2011 issue of "Big Data: innovation, competition and productivity" in the next frontier area. Helping America's healthcare industry boost its output by $300 billion a year, and help us retail industry gain more than 60% of its net profit growth.

At the Davos forum in Switzerland earlier this year, a report titled Big Data,big Impact said the data had become a new category of economic assets, like money or gold.

The Wall Street Journal, in its article, "Technological change is about to lead a new economic boom" is a bold prediction: "Once again, we are at the beginning of three grand technological changes that may be enough to rival the 20th century change, the epicenter of the three revolutions in the United States, which are big data, intelligent manufacturing and wireless networks. ”

More noteworthy is the fact that the United States has raised big data to the level of national strategy. According to the White House News of March 29 this year, the Obama administration announced an investment of 200 million dollars to launch the "Big Data research and development program", hoping to enhance the ability to collect large amounts of data and analyze extraction information.

In our country, as a new concept, large data has not been put forward by our Government to give policy support directly. However, on November 28, 2011, the Ministry of Technology released the "Twelve-Five" Planning, information processing technology as one of the four key technological innovation projects have been proposed, including mass data storage, data mining, image and video intelligent analysis, which are important components of large data. The other three key technological innovation projects, including information sensing technology, information transmission technology, information security technology, are closely related to large data.

The value and importance of large data is beyond doubt, but what new technology trends does big data bring, and what impact it has on the current power structure of the IT industry, and, crucially, how each enterprise gets the "treasure" of large data? is our real focus.
