Many people have heard it and seen it countless times. As for what is big data and what is the concept of big data, there are many introductions on the Internet. If you are interested, you can search for it yourself, so I won't explain it conceptually here. If someone doesn't quite understand the special concept, here is a popular introduction. Since it is big data, it is definitely not one or two data, but a lot of data. To put it bluntly, it is a collection of a large number of data. Where did these data come from? It is all kinds of data generated in daily business activities. Putting all these data together is big data. Because such big data are generated in daily business activities, the analysis of these data can objectively and accurately reflect the trend during this period, thus realizing a comprehensive grasp of market operation and accurate prediction of future development trends.
