Big data, "magic" for our lives.

Since 2012, the term "big data" has been more and more mentioned, which is used to describe and define the massive data produced in the era of information explosion, and to name the related technological development and innovation. Big data, artificial intelligence, cloud computing, the IT jargon that sounds very remote from popular life, is now literally changing people's lives. As Ma said, we have not known the age of the PC, mobile internet has come, not to understand the mobile Internet, when the big Data era.

What is the value of big data?

Great data value is the most important feature of large data. As long as the reasonable use of data and accurate analysis of it will bring a high value return.

Wal-Mart, for example, uses computers to analyze sales of its companies and finds that diapers and beer are positively correlated with sales. A further study by Wal-Mart found that most American families from the young father to the supermarket after work to buy diapers, will buy a few bottles of beer home to enjoy. So Wal-Mart has put paper diapers and beer together, boosting both sales; Google has used large data technologies to advance the 2009 swine flu outbreak two weeks earlier than the U.S. government's public health department. Even so, for the country, large data is more valuable, insight has defined large data as emerging strategic resources.

The rapid acquisition of valuable data from myriad and form of data requires many computer clusters to work together. The emergence of cloud computing and corresponding software in the early 21st century made the extraction of useful value in large data a reality. The large data collected in real time based on cloud computing can be distributed to dozens of, hundreds of, or even thousands of of computers, and large data that is difficult to handle and use is used, and large data is applied.

What changes will the big data bring?

In his book The Third wave of the 1980, Alvin Toffler, the American futurist, predicted that the future would produce a big bang, revealing that the big data era was coming. 2011 McKinsey summed up the big data phenomenon and released a report, igniting a big data boom.

The big data is the human and the Internet activity product, in the future it will make the big change to human's science and technology, the production, the social activity and even the human life, will have the subversive influence to the people's production process and the commodity exchange process. The essence of "big data" is based on Internet Information application, its true "magic" lies in the integration of information and industrialization, so that the production efficiency of industrial manufacturing has been greatly improved. Traditional manufacturing has large data, from "manufacturing" to "intelligent" upgrade-from the product design end to the final sales, can be intelligent analysis of large data. Enterprises can quickly respond to market demand, scientific research and development products, and precision marketing. At present, the auto industry has been using large data, hundreds of millions of of users and car-related requests for large data mining, the formation of industry indices and analysis reports to help auto enterprises understand consumer demand. With large data, traditional electronic and electrical products such as mobile phones, televisions and refrigerators have become smarter, stimulating new consumer demand.

For example, traditional statistics can only use as little data as possible to prove the largest possible facts, its coverage, randomness, representativeness and authenticity are often questioned, and the statistics from large data, its universality, representativeness and immediacy are beyond doubt. Large data impact on traditional medicine, in the future can wear medical equipment to the personal data collected in the cloud, into the personal database; The huge amount of data that accompanies personal growth and aging for decades is a valuable asset for everyone, able to quickly provide comprehensive dynamic data to help doctors make diagnoses.

How to deal with the challenges of big data?

"Big Data" cannot produce new material products or create new market demand, but can boost productivity dramatically. Large data will become a powerful weapon to enhance the competitiveness of institutions and companies, the competition between enterprises and enterprises has evolved into the competition of data, industrial era, proud of the plant and assembly line, into the information age of the server.

From 2012 onwards, the United States, Britain, Japan and other countries to actively support large data research and development. March 22, the Obama administration announced the investment of 200 million dollars to pull large data-related industries, the "Big Data Strategy" to the national strategy. As of December 2012, a total of 54 countries had joined the United States-sponsored open government programme.

The construction of large data information platform can eliminate the estrangement between government departments, the government and the citizens, and reduce the phenomenon of information island, so as to improve the efficiency of cooperative office, improve the scientificity and precision of government decision-making, and improve the ability of social administration and public service.

In China, the "Twelve-Five" development plan published by the Ministry of Industry at the end of 2011, the information processing technology is proposed as one of the four key technological innovation projects, including mass data storage, data mining, image video intelligent analysis. August 14 This year, China Data Center Industry conference convened, the purpose of the Conference is to lead the development of data centers, sharing data center innovation results, to promote data center to negotiate transactions, in order to promote the sustainable development of China's data center industry as an important support. At present, in the journey of building a well-off society in China, Industrialization, informatization, urbanization, agricultural modernization task is very heavy, the construction of the next generation of information infrastructure, the development of modern information technology industry system, promote the wide use of information network technology, is to achieve "four" synchronous development of the guarantee. The big data age has come and let's focus on big data with passion, using big data and developing big data. (City Old Science Association)

Large data

2011 Global Data If the DVD, the length of the row can travel back and forth from the Earth to the moon

Large data (Bigdata), also known as huge amounts of data, massive data, refers to the amount of data involved in the large scale to the current mainstream software tools, within a reasonable time to capture, manage, process and collate information.

International data companies define the four characteristics of large data: massive data size (vast), fast data flow and Dynamic Data systems (velocity), diverse data types (produced), and huge data value (value). In terms of sheer volume of data, the time required for global IP traffic to reach 1eb is 1 years in 2001, 1 days in 2013 and only half a day in 2016. The world's new data is increasing by 40% a year, and global information can double every two years. According to the 2012 Internet Data Center published in the "Digital Universe 2020" report, 2011 Global Data volume has reached 1.87ZB (1zb=10 trillion billion bytes), if the data to be carved into a DVD, the length of the line up from the Earth to the moon between a back and forth distance.
