How to confirm that big data is a secret connector?

Big data is mainly investigated through data provided by operators. Generally speaking, if the individual's cell phone signal and the patient's cell phone signal stay together in the same space-time grid (generally 800 meters ×800 meters) for more than a certain time, then they will be judged as close contacts, that is, the so-called space-time companions. If it is confirmed to be a space-time companion, generally speaking, isolation is not required, and only two inspections are required within three days.

The convenience of big data

Each of us will produce data and traces through the use of the Internet or mobile terminals, which reflect a comprehensive evaluation of a person's income, class, consumption concept, hobbies, education level and so on. By collecting these data, enterprises conduct a series of analysis and matching, and finally push you "the goods or services they think you should need".

Today, big data is infiltrating into various industries at a steady pace. In the future, there will be more and more applications of big data in our lives. Whether it is an enterprise or an individual, only by leveraging big data and making efficient use of the obtained information can development maintain a strong momentum and be endless. The era of big data is coming, and it is changing our lives.
