Big Data's smallest basic unit bit.

The strategic significance of Big Data technology does not lie in the mastery of huge data information, but in the specialized processing of these meaningful data. In other words, if the big data is compared to an industry, the key to profitability of this industry lies in improving the "processing capability" of the data, and realizing the "value-added" of the data through "processing". "

Technically, the relationship between big data and cloud computing is as inextricably linked as the positive and negative sides of a coin. Big data necessarily cannot be processed by a single computer, and must use a distributed architecture. It is characterized by distributed data mining of massive amounts of data. But it must rely on cloud computing's distributed processing, distributed database and cloud storage, and virtualization technologies.

Some people compare data to a coal mine that contains energy. Coal according to the nature of coking coal, anthracite, fat coal, poor coal and other classifications, and open-pit coal mines, deep mountain coal mines and different mining costs. Similarly, big data is not "big", but "useful". The value content and mining cost are more important than the quantity. For many industries, how to utilize this large-scale data is the key to winning the competition.
