Introduction:

Big Data, or Big Data, refers to information that is so large in size that it cannot be captured, managed, processed, or organized in a reasonable amount of time through mainstream software tools, and is used to help businesses make more positive decisions.

Definition of data:

The research organization Gartner defines "big data" as follows. "Big data" is the need for new processing models in order to have a stronger decision-making power, insight discovery and process optimization capabilities to adapt to the massive, high growth rate and diversity of information assets. The strategic significance of big data technology lies not in the mastery of huge data information, but in the specialized processing of these data containing meaning.

In other words, if big data is compared to an industry, the key to the profitability of this industry lies in the improvement of the processing capability of the data, and the "value-added" of the data is realized through "processing". Technically, the relationship between big data and cloud computing is as inextricably linked as the positive and negative sides of a coin.
