Comment: Big data is more prevalent in daily life than you think

It is really an interesting article, I really like this kind of article because it is more relevant to our lives.

Most of the people serf online, no matter to play games, listen to music, watch videos, shopping online, or any other activities. When we do anything online, we will leave the records about what we do and what we search so that companies can use the information that we left to realize our interest and to help them customize our home page on the website and in this way, we can have better online entertainment experience.

Big data can also help to improve public safety, professors use big data to
keep people safe. By collecting data, professors can analyze and predict when the crime might happen, this way, there will be fewer people get injured in the crime.

Because of the big data, sometimes we will get some advertisements by e-mail from our favorite online retailers, and this can reduce the time that we search the product that we want online during the time, although now it is more convenient to shop online, but searching for the products that we want still spend us a lot of time.

Last, big data improved the whole world's medical care, and this is really important to our society. Big data can not only help the doctor to track the patient's situation remotely, but also help patients from afar, and this can save more patients' lives. Also, sharing knowledge with others can isolate and fight the disease before it spreads to the epidemic.
