The establishment of big data is imperfect and wrong. Most of the analysis and forecast reports of many companies are completely fabricated, but it is certain that some of them are mixed with subjective judgment factors. Why is this analysis report from so-called big data more dangerous? Because now a large number of people are not interested in the so-called experts around them. More people are more willing to believe that "data speaks". Even if the source of this data itself is worth thinking about. This type of big data analysis and reporting includes some applications, which are often more spreading and explosive. In the period when the Internet is not very popular, although judging by personal experience often has a lot to do with this person's integrity, after all, without the media of the Internet, his personal views will not affect many people. But the application and analysis report under big data are different. Because it is an internet-based media, the report produced by a company will spread explosively in a short time. Its influence is amazing. There has even been a phenomenon of repeated mistakes. However, because the country does not have very high supervision and threshold requirements for such reports, many companies often use strong tendencies to polish their positions in order to win market and popularity. Such reports and applications will only mislead more people. Big data has been developing and evolving since it was put forward, and various application cases are varied, most of which end in failure.

By its nature, big data is junk information. Especially static data, like a stagnant pool, is worthless. Only by making all links flow and formulating strict production process standards can we have more opportunities to make the data true.
