1、The development and tendency of Big DataTang Xia(Guilin University of electronic technology, electronicengineering?and?automation, Guilin)Abstract: "Big Data"?is the most popular IT word after the "Internet of things"?and "Cloud computing". From the source, development,

2、 status quo and tendency of big data, we can understand every aspect of it. Big data is one of the most important technologies around the world and every country has their own way to develop the technology.Key words : big data; IT; technology1 The source of big dataDespite the famous futurist Toffle

3、r propose the conception of “Big Data ” in 1980, for a long time, because the primary stage is still in the development of IT industry and uses of information sources, “Big Data” is not get enough 1 attention by the people in that age .2 The development of big dataUntil the financial crisis in 2008

4、force the IBM ( multi-national corporation of IT industry) proposing conception of “Smart City ” and vigorously promote Internet of Thingsand Cloud computing so that informationdata has been in a massive growth meanwhile the need for the technology is very urgent. Under this condition, some American

5、 data processing companies have focused on developing large-scale concurrent processing system, then the “Big Data” technology become available sooner and Hadoop mass data concurrent processing system has received wide attention. Since 2010, IT giants have proposed their products in big data area. B

6、ig companies such as EMC、HP、 IBM、Microsoft all purchase other manufacturer relating to big data in order to achieve technical integration 1 . Based on this, we can learn how important the big data strategy is. Development of big data thanks to some big IT companies such as Google 、Amazon、China mobil

7、e 、Alibaba and so on, because they need a optimization way to store and analysis data. Besides, there are also demands of health systems 、geographic space remote sensing and digital media2 .3 The status quo of big dataNowadaysAmerica is in the lead of big data technology and market application.USA f

8、ederal government announced a “ Big Data 's research and development ” plan in March,2012, which involved six federal government department the National Science Foundation, Health Research Institute, Department of Energy, Department of Defense, Advanced?Research?Projects?Agency and GeologicalSur

9、vey in order to improve the ability to extract information and viewpoint of big data 1 . Thus, it can speed science and engineering discovery up, and it is a major move to push some research institutions making innovations.The federal government put big data development into a strategy place, which

10、has a big impact on every country. At present, many big European institutions is still at the primary stage to use big data and seriously lack technology about big data. Most improvements and technology of big data are come from America. Therefore, there are kind of challenges of Europe to keep in s

11、tep with the development of big data. But, in the financial service industry especially investment banking in London is one of the earliest industries in Europe. The experiment and technology of big data is as good as the giant institution of America. And, the investment of big data has been maintai

12、ned promising efforts. January 2013, British government announced 1.89 million pound will be invested in big data and calculation of energy saving technology in earth observation and health care 3 .Japanese government timely takes the challenge of big data strategy. July 2013, Japan 's communica

13、tions ministry proposed a synthesize strategy called “Energy ICT of Japan ” which focused on big data application. June 2013, the abe cabinet formally announced the new IT strategy “The announcement ofcreating the most advanced IT country”. This announcement comprehensivelyexpounded that Japanese ne

14、w IT national strategy is with the core of developing opening public data and big data in 2013 to 20204 .Big data has also drawn attention of China government.Guiding?opinionsof the State Council on promoting?the healthy and orderly development?of the?Internet of things promote to quicken the core t

December 2012, the national development and reform commission add data analysis software into special guide, in the beginning of 2013 ministry of science and technology announce

16、d that big data research is one of the most important content of“973 program ” 1 . This program requeststhat we need to research the expression, measure and semantic understanding of multi-source heterogeneous data, research modeling theory and computational model, promote hardware and software syst

17、em architecture by energy optimal distributed storage and processing, analysis the relationship of complexity 、 1calculability and treatment efficiency. Above all, we can provide theoryevidence for setting up scientific system of big data.4 The tendency of big data4.1 See the future by big dataIn th

18、e beginning of 2008, Alibaba found that the whole number of sellers were on a slippery slope by mining analyzing user-behavior data meanwhile the procurement to Europe and America was also glide. They accurately predicting the trend of world economic trade unfold half year earlier so they avoid the

19、financial crisis2 . Document 3 cite an example which turned out can predict a cholera one year earlier by mining and analysis the data of storm, drought and other n atural disaster .4.2 Great cha nges and bus in ess opport un itiesWith the approval of big data values, gia nts of every in dustry all

20、spe nd more money in big data in dustry. Then great cha nges and bus in ess opport un ity4comes .In hardware in dustry, big data are facing the challe nges of man age, storage and real-time an alysis. Big data will have an importa nt impact of chip and storage in dustry, besides, some new in dustry

22、.4.3 Developme nt directi on of big dataThe storage tech no logy of big data is relatio nal database at primary. But due to the canonical design, friendly query Ianguage, efficient ability dealing with online affair, Big data dominate the market a long term. However, its strict design pattern, it en
