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 attention by the people in that age 1 .2 The development of big dataUntil the financial crisis in

4、 2008 force the IBM ( multi-national corporation of IT industry) proposing conception of“Smart City " and vigorously promoteInternet of Things and Cloud computing so that information data has been in a massive growth meanwhile the need for the technology is very urgent. Under this condition, so

5、me American 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

6、big data area. Big companies such as EMC HR IBM、Microsoft all purchase other manufacturer relating to big data in order to achieve technical integration1 . Based on this,we can learn how important the big data strategy is. Development of big data thanks to somebig IT companies such as Google、Amazon

7、China mobile、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 applica

8、tion. USA federal 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 Geologic

Thus, itcan 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, whic

10、h 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

This program requests that we need to research the expression, measure and semantic understanding of multi-source heterogeneous data, research modeling theory and computational model, promote hardware

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

18、re by big dataIn the beginning of 2008, Alibaba found that the whole number of sellers wereon 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

19、so they avoid the financial crisis 2 . 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 natural disaster 3 .4.2 Great changes and business opportunitiesWith the approval of big data values, giants of every

20、industry all spend more money in big data industry. Then great changes and business opportunity comes4.In hardware industry, big data are facing the challenges of manage, storage and real-time analysis. Big data will have an important impact of chip and storage industry, besides, some new industry w
