Big Data Era refers to the processing and analyzing and storing of massive data using relevant algorithms, discovering value from massive data and serving life and production.

The so-called big data era, from the literal meaning of the word is not difficult to understand, the data is very large, the amount of information is relatively large, which is also the rapid development of the Internet brought about by the change. Just from the communication above we can see, the previous 2G, 3G can meet the people to use, to the later 4G, the development of the network, people are able to access more and more information through the Internet, and now began to introduce 5G, the era of big data, after all, to accommodate and accept more information.

Thinking change

When the processing technology of data has changed radically, the era of big data, our thinking must also change.

The first change in thinking: to utilize all of the data and no longer rely on just some of it, i.e., not a random sample, but all of it.

The second change in thinking: the only way we can open a new window on the world is to accept imprecision, i.e., not precision, but confounding.

The third change in thinking: not everything has to know the reason behind the phenomenon, but to let the data "speak for itself", i.e., not causality, but correlation.
