2. At the foundation stage, first of all, we should systematically learn basic concepts and knowledge. At this time, it is suitable to look at the materials with complete system and easy to understand (to avoid being scared to give up learning at the beginning). After we have made clear the basic concepts and common terms, we can go to some information websites and official account to find out some latest block chain applications and big events.
3. Big data (mega data), or massive data, refers to the massive, high growth rate and diversified information assets that need new processing mode to have stronger decision-making power, insight and process optimization ability. In "the age of big data" written by Victor Myer Schoenberg and Kenneth kukeyer, big data refers to the use of all data for analysis and processing instead of the shortcut of random analysis (sampling survey). The 5V characteristics of big data: volume, velocity, variety, value and veracity
"big data" refers to a large group of data collected from many sources in multiple forms, which is often real-time. In the case of business to business sales, the data may come from social networks, e-commerce websites, customer visit records, and many other sources. These data are not the normal data group of the company's customer relationship management database
from a technical point of view, the relationship between big data [1] and cloud computing is as inseparable as the positive and negative sides of a coin. Big data can not be processed by a single computer, so it must adopt distributed computing architecture. It is characterized by massive data mining, but it must rely on cloud computing distributed processing, distributed database, cloud storage and / or virtualization technology In the era of big data [4], written by Victor Myer Schoenberg and Kenneth kuckye, big data refers to the 4V characteristics of big data: volume, velocity, diversity and value
as early as 1980, Alvin Toffler, a famous futurist, enthusiastically praised big data as "the colorful movement of the third wave" in his book the third wave. However, "big data" has only become a popular word in the Internet information technology instry since 2009. The Internet data center of the United States points out that the data on the Internet will grow by 50% every year and double every two years. At present, more than 90% of the data in the world is generated in recent years. In addition, data does not simply refer to the information released by people on the Internet. There are countless digital sensors on instrial equipment, automobiles and electricity meters all over the world, which measure and transmit the changes of position, movement, vibration, temperature, humidity and even the chemical substances in the air at any time, and also proce massive data information
the meaning of big data is accompanied by the increasingly popular network behavior of human beings. It is collected by relevant departments and enterprises, and contains the real intention and preference of data procers. It is non-traditional structure and meaning of data. On May 10, 2013, 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 give a speech at the party. Ma Yun said that before we have a clear idea of the PC era, the mobile Internet is coming. Before we have a clear idea of the mobile Internet, the era of big data is coming
with the upsurge of big data era, Microsoft has proced a data-driven software, which is mainly to save resources and improve efficiency for engineering construction. In this process, 40% of the world's energy can be saved. Regardless of the prospect of this software, starting from the Microsoft team's dedicated research, we can see that their goal is not only to save energy, but also to pay more attention to intelligent operation. By tracking the huge amount of data accumulated by heaters, air conditioners, fans and lights, we can capture how to eliminate energy waste“ Give me some data and I can make some changes. If you give me all the data, I can save the world. " Microsoft Smith said. And intelligent building is what his team focuses on
it is also a great challenge for network architecture and data processing ability to "purify" useful information from massive data. After several years of criticism, questioning, discussion and speculation, big data finally ushered in its era. On March 22, 2012, the Obama administration announced that it would invest 200 million US dollars to promote the development of big data related instries, upgrading the "big data strategy" to a national strategy. The Obama administration even defines big data as "the new oil of the future."
the era of big data has come, and it will bring great waves of change in many fields. But we should calmly see that the core of big data is to mine the value contained in the data for customers, rather than the stacking of software and hardware. Therefore, the research on big data application mode and business model in different fields will be the key to the healthy development of big data instry. We believe that with the overall planning and support of the state, through the local governments to formulate the development strategy of big data instry according to local conditions, and through the active participation of domestic and foreign it leading enterprises and many innovative enterprises, the future development prospect of big data instry is very broad
big data is just a kind of appearance or feature of the development of the Internet to the present stage. There is no need to mythologize it or keep awe of it. Against the backdrop of the curtain of technological innovation represented by cloud computing, these data, which were originally difficult to collect and use, are easy to be used. Through continuous innovation in all walks of life, Big data will graally create more value for mankind[ 1]
significance
today's society is a society of rapid development, with advanced science and technology, information circulation, closer communication between people, and more convenient life. Big data is the proct of this high-tech era. Ma Yun, founder of Alibaba, mentioned in his speech that the future era will not be the IT era, but the era of DT. DT is data technology, which shows that big data plays an important role for Alibaba group
some people compare data to coal mines that contain energy. According to the nature of coal, there are coking coal, anthracite, fat coal, lean coal and so on, while the mining cost of open-pit coal mine and deep mountain coal mine is different. Similarly, big data is not "big", but "useful". Value content and mining cost are more important than quantity. For many instries, how to use these large-scale data is the key to win the competition
