Qiangzi fortune-telling

Why did you have to do divination in ancient times when you were in trouble?

Ancient divination, so how do modern investment look at seed stocks and market?

In modern times, you don't have to do everything yourself. Aren't you going to have one or two before you do it? Online shopping doesn't read reviews? Don't compare prices?

These are no different from divination. It's all big data analysis.

The word "arithmancy" comes from two Greek etymologies "arithmo" which means "number" and "mancy" which means "wisdom". This fortune-telling method has been used by magicians and wizards for more than 20 thousand years to help people analyze their abilities and develop their wisdom and talents.

"Big data" refers to a huge data set collected from many sources in various forms, often in real time. In the case of business-to-business sales, these data can be obtained from social networks, e-commerce websites, customer visit records and many other sources. These data are not the normal data set of the company's customer relationship management database.

Technically, the relationship between big data [1] and cloud computing is as inseparable as the two sides of a coin. Big data can't be processed by a single computer, so distributed computing architecture must be adopted. It is characterized by mining massive data, but it must rely on distributed processing of cloud computing, distributed database, cloud storage and/or virtualization technology. (In "The Age of Big Data [4]" written by Victor Mayer-schoenberg and Kenneth Cookeye, big data refers to the method of using all data, not the shortcut of random analysis (sampling survey). The 4V characteristics of big data are: volume (mass), speed (high speed), diversity (diversity) and value (value).

As early as 1980, alvin toffler, a famous futurist, enthusiastically praised big data as "the cadenza of the third wave" in his book The Third Wave. However, since about 2009, "big data" has become a hot word in the Internet information technology industry. According to the data of American Internet Data Center, the data on the Internet will increase by 50% every year and double every two years. At present, more than 90% of the data in the world are only produced in recent years. In addition, data does not only refer to the information that people publish on the Internet. There are countless digital sensors on industrial equipment, automobiles and electric meters all over the world, which can measure and transmit the changes of position, movement, vibration, temperature, humidity and even chemicals in the air at any time, and also produce a huge amount of data information.

The significance of big data is that it is accompanied by the increasingly popular network behavior of human beings, collected by relevant departments and enterprises, contains the true intentions and preferences of data producers, and has non-traditional structure and significance. 2065438+May 13, Ma Yun, Chairman of the Board of Directors of Alibaba Group, will step down as CEO of Alibaba Group at the 10th anniversary party of Taobao, and deliver a speech before leaving office at the party. Ma Yun said that when people didn't understand the PC era, the mobile Internet came. When they didn't understand the mobile Internet, the era of big data came.

With the upsurge of big data era, Microsoft has produced data-driven software, mainly to save resources and improve efficiency in engineering construction. In this process, it can save 40% energy for the world. Aside from the prospect of this software, we can see that the goal of the Microsoft team is not only to save energy, but also to pay attention to intelligent operation. By tracking a large amount of data accumulated by heaters, air conditioners, fans and lamps, we can capture how to prevent energy waste. "Give me some data and I can make some changes. If you provide me with all the data, I can save the world. " Microsoft Smith said this. Intelligent building is exactly what his team is concerned about.

Extracting useful information from massive data is also a great challenge to network architecture and data processing ability. After several years of criticism, questioning, discussion and hype, big data has finally ushered in its own era. 20 12 On March 22nd, the Obama administration announced that it would invest 200 million US dollars to promote the development of big data-related industries and upgrade the "big data strategy" to a national strategy. The Obama administration even defined big data as "the new oil of the future".

The era of big data has arrived, and it will set off a huge wave of change in many fields. However, we should calmly see that the core of big data is to tap the value contained in the data for customers, rather than the accumulation of software and hardware. Therefore, the research on the application model and business model of big data in different fields will be the key to the healthy development of big data industry. We believe that under the overall planning and support of the country, through the development strategy of big data industry formulated by local governments according to local conditions, and through the active participation of leading IT enterprises at home and abroad and many innovative enterprises, the future development prospects of big data industry are very broad.

Big data is just a representation or feature of the development of the Internet at this stage. There is no need to myth it or keep it in awe. Under the background of technological innovation represented by cloud computing, these data, which were originally difficult to collect and use, have become easy to use. Through continuous innovation in all walks of life, big data will gradually create more value for mankind.
