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

Technically, the relationship between big data and cloud computing is as inseparable as the front and back of a coin. Big data cannot be processed by a single computer, and it must adopt a distributed architecture. It is characterized by distributed data mining of massive data. But it must rely on the distributed processing of cloud computing, distributed database, cloud storage and virtualization technology.

The word "big data" is mentioned more and more in vain. People use it to describe and define the massive data generated in the information explosion era of Xinzhi, which is called the era of big data.

With the advent of the cloud era, big data has attracted more and more attention. Big data is usually used to describe a large amount of unstructured and semi-structured data created by a company. It will take too much time and money to download it to a relational database for analysis.
