Big data (数据) technology has been working widely for more than ten years. Actually all activities of our daily lives have some kinds of online footprints. Both companies and persons are trying to get value out of big data.
Big data means large sets of data collected from different areas. The data then will be studied to get useful information, which can be turned into value. Areas of use of big data cover a lot of industries, such as healthcare, business services, transport, and customer services. Take a supermarket chain as an example. The chain managers study the data of thousands of customers across hundreds of stores, possibly finding hidden buying patterns. In turn, if products are properly placed, it might result in more sales.
As we shall see shortly, much of the data is produced largely in real-time. These may be cross-national online business websites with thousands of deals per minute, or social media platforms (平台) with millions of users, with more than billions of posts a day.
Besides, the big data with AI technology comes into play. Business services were able to use the information about their customers, like banking records and spending habits to spread their businesses and build new services, using big data about their customers.
In healthcare, examples are medical treatment improvement and outbreak progression (疫情进展). Firstly, big data can analyze (分析) a large amount of information, and then doctors can make some plans according to these data so that they can provide cheaper and better treatment. Secondly, it could predict outbreaks of future illness and help to reduce the influence of disease.
So we can expect more organizations to recognize the value of big data. This means that the need for experts in this field is expected to grow. What changes will big data bring to us?
