Big?Data refers to "massive, complex collections of data that cannot be extracted, stored, searched, ****enjoyed, analyzed, and processed with existing software tools." The industry often uses the 4 V's (i.e. Volume, Variety, Value, Velocity) to summarize the characteristics of Big Data.

The volume of data is huge (Volume). As of today, the volume of data for all printed material produced by humans is 200 petabytes (PB), and the volume of data for all words spoken by all humans throughout history is about 5 EB (1 EB = 210 PB).

Variety of data types. Compared with the text-based structured data that used to be easy to store, there is an increasing amount of unstructured data, including web logs, audio, video, images, geolocation information, etc. These multiple types of data place higher demands on data processing capabilities.

Low value density (Value). The level of value density is inversely proportional to the size of the total amount of data. How to complete the value of the data more quickly through powerful machine algorithms "purification" has become the current big data background of the urgent need to solve the problem.

Fast processing speed (Velocity). Big Data is distinguished from traditional data mining by its most significant feature. According to IDC's "Digital Universe" report, global data usage is expected to reach 35.2 ZB by 2020.

Social networks, which enable us to increasingly observe complex patterns of behavior in human societies from data. Social networks, for big data, provide the first hand information to gather and analyze. The value of big data is to mine and analyze users' behavioral habits and preferences from the back of the data, to find products and services that are more in line with users' tastes, and to adjust and optimize themselves in a targeted way to meet users' needs.

So, based on the above concepts, we can see the industrial changes of big data:

1?Industrial integration and new industrial drive brought by the flywheel effect of big data

2?New information aggregation brought by the complete change of the way of obtaining information

3?New information promotion brought by the complete change of the way of pushing information

4? ?Precision marketing

5?Third-party payment? --? Micro-credit, online crowdfunding as the representative of the Internet finance brought about by the comprehensive Internet financial reform

6?Trend of vertical integration of industries and the subsequent reconstruction of the industrial ecology

7?Corporate reform and the reshaping of the internal value chain, the expansion of the external boundaries of the industry

8?Openness of the government and institutions at all levels, transparency, and the subsequent centralized management and internal mechanism adjustments

9? internal restructuring

9?New services brought about by data innovation
