The value of big data lies in the application. He can solve problems and predict the future by means of data collection. Promoting the implementation of the national big data strategy is one of the current national concerns. How to ensure data security and speed up the construction of digital China, big data has received unprecedented attention, this article will describe the three major tortures of big data.

From mobile payments to the sharing economy, big data is accelerating the reshaping of many aspects of mass life; from the Internet of Everything to the smart city, big data is profoundly affecting all areas of economic development, social governance, and state management. Understanding big data, mastering big data, and using big data is a real issue at the moment, and it means more judgment and guidance for the future.

Big data is gaining unprecedented attention. At the end of 2017, General Secretary Xi Jinping emphasized in the second collective study of the Political Bureau of the CPC Central Committee that it will promote the implementation of the national big data strategy, accelerate the improvement of digital infrastructure, promote the integration and open sharing of data resources, ensure data security, and accelerate the construction of digital China. In the past year, Guizhou, Hainan, Sichuan and other places have successively released work plans for promoting big data development or relevant local regulations to promote and guarantee the orderly advancement of big data development, and all kinds of convenience applications have emerged, and industrial agglomeration has obviously accelerated.

How is the current status of big data development in China – is data application playing its due role? Is data sharing shared reasonably sufficient? Is personal data privacy protection comprehensive?

-The application field is not extensive

- Regional level imbalance

- Industry integration is not deep

Annual bills, listening to songs, travel trajectories... At the beginning of the year, several Internet application platforms launched a “personal summary” of user usage, what did you buy, how many times you went to the restaurant, what songs you heard, and where you went... ...big data seems to know yourself better than the user. Although questionable, but behind the interesting "user portrait", big data applications are getting more and more popular in ordinary people's homes.

The "Big Data Industry Development Plan (2016-2020)" issued by the Ministry of Industry and Information Technology pointed out that at present, big data still has problems such as the application field is not extensive, the application level is not deep, and the understanding is not in place. In order to solve more pains in demand, big data urgently needs to break through the industry's uneven development level, unbalanced application areas, and in-depth business integration.

Statistics from the Big Data Industry Research Center of CCID Consulting Co., Ltd. show that the big data applications in the three major fields of Internet, finance and telecommunications account for more than 70% of the total scale of various industries; the health care field and the transportation field have been continuously in recent years. On the shelves of "new applications, but the proportion of the industry is relatively small; and in many other areas of people's livelihood, big data applications are still at a shallow level of information, the level of industry development is uneven.

Shanghai Putuo District promotes the “Community Governance Cloud Platform” system, and the grassroots big data makes the community service “handheld” available; the country’s first tourism big data public service platform “Hangzhou Tourism Data Online” is launched, and visitors can learn the real-time attractions through mobile phones. Congestion, hotel ratings, etc... In general, big data applications in the eastern region are “refreshed” faster. CCID Consulting's statistics show that the big data industry development in Beijing, Jiangsu, Zhejiang, Shandong and Shanghai leads the country, while Yunnan, Jilin, Hebei, Inner Mongolia, Guangxi and other provinces are relatively lagging behind, and the development of big data application areas is not balanced. The problem cannot be ignored.

The value of big data lies in the application. The key to “playing big data” is the deep integration of big data technology and business. “At present, big data has not been deeply integrated with the business in many industries, and the application scenarios are not innovative enough. Big data technicians need to improve their business knowledge and experience.” Data technology and application service provider percentage data chief data scientist Du Xiaomeng said that many domestic industries Big data technology is still only used in local services. Only data mining and analysis technologies are mastered. If the technology and services cannot be comprehensively and deeply integrated, the true value of data applications cannot be fully discovered.

The Big Data Industry Development Plan (2016-2020) proposes that by 2020, the revenue of big data-related products and services will exceed 1 trillion yuan, and the average annual compound growth rate will remain around 30%. Big data is in innovation and entrepreneurship, government management. And extensive application in areas such as people's livelihood services. How to better integrate, analyze and apply on the basis of collecting and storing big data in the future will become a key topic for optimizing the "data brain".

The vitality of big data lies in discovering problems, perceiving risks, establishing connections, solving problems, and predicting the future. At present, domestic big data applications focus on data collection, and there is still much room for improvement in basic statistical analysis, risk perception and prediction. At the same time, it is impossible to blindly pursue big data without clearing the specific business application scenarios, but to use the application scenario as the traction, only to collect non-analysis or one-sided pursuit of large and complete, is not conducive to big data to promote its promotion of productivity. effect. In addition, while big data is widely used in innovation, entrepreneurship, government management, and people's livelihood services, it should also be recognized: how big is the impact of big data on society, and how big should society respond, regulate, and constrain the development of big data. .
