The big Data age is coming, are you ready?

During the 2014 session, CCTV news network set up the "two Big Data" plate, daily through the government work report related topics and discussion characteristics of large data analysis, give different forms, different content of concern and economic and social development forecasts and other specific vivid analysis chart, refreshing. "Big Data" also followed the hot word list. So what is the value of big data?

A how big is the data?

In today's information network era, people's online operation, ordinary every move, the operation of the machine, the nature of any change will produce a lot of data. These data are large and complex, and are difficult to handle with existing computing tools, which are known as "Big Data".

Let's take a look at these: all the content that the Internet produces on a single day can be 168 million DVDs, more than 200 billion emails a day, 2 million community posts, 378,000 mobile phones, Tencent registered more than 700 million users, and more than 100 million online. Create " Safe City ", a camera running for an hour, the resulting data is 3.6G; The hospital examines a CT to produce several G-image data; In the digital industrial design today, the design of a plane, hundreds of thousands of parts of the size, size, shape are data; every day we call and pay by credit card, we will produce a lot of data. Imagine how big the data would be. According to the IBM study, 90% of all the data available to the entire human civilization have been generated in the past two years. By the year 2020, the world's data will be 44 times times the size of today's. Large data has four typical characteristics, such as large data volume, wide variety, fast data change, low value density, traditional processing methods and software tools can not analyze these large amount of data, and need innovative data processing methods and software analysis tools.

It is not hard to understand how much data is produced. From the popularity of smartphones to the popularity of two-dimensional codes, to the advent of wearable equipment, our basic necessities can be electronic, the vast number of data also followed; industrial equipment, automobiles, electric meters on the numerous sensors, at any time to measure and transmit a variety of information, will produce a huge amount of data; The growing sophistication of mobile phone fingerprint identification sensors, olfactory sensors, and even new technologies that can perceive emotions, all make it possible for human activity and the physical world to become digital.

So "big" data, how to store it? Of course, this is thanks to the development of technology: The Moore's Law, which reflects the progress of computer hardware technology, is described in the same way that the integration of integrated circuits increases by one times every 18 months, and prices fall by half. Falling costs contribute to the storage of large data. At the same time, with the development of new media such as quantum computing and optical computing, data storage capability will be greatly improved.

B the value of large data

If you are a member of the Amazon, you may find that "guess what you Like" recommended books are often of interest to you; if you intend to buy a network of air purification equipment recently, and the relevant information on the Internet, you will find your Taobao home, there are many sales of air purifier push, and even on other sites, Will pop up information about the air purifier from time to time.

This is due to the merchant's "Big data" development and application.

Look at "Baidu" "micro-letter" "Taobao" these are our work and life can not be separated from the application of it: Baidu data is demand data, what search needs what; Tencent micro-letter reflects interest and relationship data, and Taobao data form trading data, if you have the same interest and relationship, demand and transaction data, Can make a person's behavior clear. Similarly, all walks of life as long as the data is large enough to foresee the future is not difficult.

Some people say that "anticipating the future" is the core value of big data. So what is the value of anticipating the future that can bring about changes in our lives?

Take "Baidu migration" as an example. January 26, "Baidu Migration" website officially online. On the Chinese map of the homepage, every jumping point is the destination for people to start and arrive. Clicking on any city will show the largest number of emigration and immigration figures in the city over the past 8 hours. "Baidu Migration" is the mobile phone users of the location of information summarized into large data analysis, thus outlining the migration trajectory of people. This information has important value in analyzing the direction of population migration, the process of urbanization and the transportation deployment of Spring Festival.
