We are facing a time of big data. In the past, in the small data age, the human judgment of things is based on intuition, experience and imagination, and prejudices are everywhere. When the information explosion accumulates to the qualitative change, the large data will apply the mathematical algorithm to the massive data, in order to revise the prejudice and intuition of human and predict the future.
This shift is the biggest contributor to big data, from making decisions based on one's own judgment and developing to relying on data for decisions and gaining competitive advantage, which will lead to huge management changes. Because the data itself does not lie, by letting the data decide, making scientific decisions, so that the social sciences really become a science.
On the other hand, the data is becoming the core asset of the enterprise, which may be counted into the balance sheet in the future. China's top three internet companies, Tencent, Alibaba [Weibo] and Baidu [Weibo], and the most owned data assets-Tencent has the largest network data, Alibaba has the largest network trading data, and Baidu has the largest search data assets.
Foreign media forecasts 2013 will be the world's largest data year. It is clear that this coming data revolution will bring unprecedented innovations and challenges to enterprise development models and decisions.
In the Third century B.C., King Soter of Egypt created the Library of Alexandria, which, in its heyday, had a collection of 700,000 volumes, which Egypt called "The beacon of human knowledge, the intersection of civilizations". In today's view, the library of Alexandria can be said to be the world's largest knowledge and data center at the time, and the classification, collation and storage of these data cost hundreds of years.
1439, the Germans Gutenberg invented the printing press, from 1453 to 1503, about 8 million books were printed in 50 years, more than any other manuscript in Europe since 1200, and Europe's information store has grown by one-fold in 50 years, now about every three years.
By 2013, the data stored in the world will reach 1.2ZB (ZB, ze byte, 10 trillion bytes), if the data are all recorded in the book, these books can cover the entire United States 52 times, if stored on a CD-ROM, these discs can be stacked into 5 piles, each can reach the moon.
The amount of data around the world is accelerating at a geometric level, thanks to Moore's law. In 1965, Moore, founder of Intel [Weibo], suggested that the number of transistors that could be accommodated on an integrated circuit would increase by one time every 18 months, and the performance would rise by one fold, when prices were unchanged. In other words, every dollar will be able to buy the performance of the computer, each 18 months over twice. The result of Moore's law is that computers are running faster, more storage space and cheaper. Data show that in the past 50 years, the cost of data storage has been cut by half every two years, while the storage density has increased by 50 million times times, the human storage information growth rate is 4 times times faster than the 9374.html "> World economy."
At the same time, the development of data recording aims to meet the human desire to measure, record and analyze the world. Records and measurements can reproduce human activities, laying the groundwork for projections and plans. For hundreds of of years, metering has expanded from length and weight to area, volume and time. The Arab armies conquered the Indian Punjab area around 700 A.D., and they were surprised to find that India's counting method was quite advanced. Based on the difference between the position of the same digit symbol and other digital symbols, the Indian mathematician has defined the concept of the digital position, and the descendants have improved and invented the 1,2,3,4,5,6,7,8,9,0 10 symbols, which is the basis of the counting. In the Crusades, the European knights brought the counting method back to Europe from the Arab region. In 1000, Pope Hilvest began to advocate the use of Arabic numerals. By the late 16th century, the counting method had been popularized in Europe.
By the 19th century, as scientists invented new tools to measure and record the emergence of natural phenomena such as electricity, air pressure, temperature, and audio, science has been inseparable from quantification, and we are in an age where everything needs to be measured, divided and recorded. With the development of computer technology, the algorithms that drive all kinds of systems are progressing rapidly, and in many fields, the progress of these algorithms is better than that of chip. Data show that the capacity of computer processing data is growing 9 times times faster than the world economy. Arithmetic gives new meaning to data, since data can be recorded and analyzed and recycled at this time.
During the ancient Roman Empire, only the government had the ability and the will to collect and analyze large-scale data such as population and economy. By the 21st century, as data storage and access became simpler, private-sector companies began to have large numbers of data, such as Google's Daily processing of 24PB (PB, Byte, petajoules bytes) of data, equivalent to hundreds of thousands of data contained in all paper publications of the National Library. Private holding companies, especially internet companies, can collect a lot of valuable data and have a strong interest drive to exploit the data, so internet companies are logically the leading practitioners of the latest technology, and the "big data" concept emerges.
