The era of data cognition means that people no longer objectively know, feel and understand the essence of things, but only decide their preferences based on data. This is the best era and this is the worst era. With the progress of the information age, information data resources have become the most valuable wealth in recent years. While we are in an era of big data with explosive growth of information, the speed of data transmission is far beyond our control. Big data has a profound impact on politics, economy and culture, and the era of big data also presents us with new opportunities and challenges.
Big data is a large amount of high-speed and changeable information. It needs new processing methods to promote stronger decision-making ability, insight and optimal processing. Big data provides unprecedented space and potential for enterprises to gain more profound and comprehensive insight. Today's society is a fast-growing society, with advanced science and technology, information circulation, more and more close communication between people, and more convenient life. Big data is the product of this high-tech era. Although big data is bred from the growing popularity and maturity of information and communication technology, its impact on social and economic life is not limited to the technical level. In essence, it provides a new way for us to view the world, that is, decision-making behavior will increasingly be based on data analysis, rather than relying more on experience and intuition as in the past. With the help of big data and related technologies, we can carry out targeted marketing for customers with different behavioral characteristics, even from recommending a product to some suitable customers to recommending some suitable products to one customer, so that we can focus more on customers and carry out personalized and accurate marketing.
