The characteristics of data of big data are diversity, variability, etc.

One of the characteristics of big data is diversity, the data of big data comes from a wide range of sources, including structured data, unstructured data, semi-structured data, etc., and the different types of data make big data have different characteristics and uses. The value of big data lies in its ability to record and process a large amount of fragmented data, and the laws and trends in the data can be discovered through big data analysis, providing support for decision-making and prediction.

One of the characteristics of big data is variability, which means that there are difficulties and challenges in processing and managing data effectively. Due to the complexity and variability of data, traditional data processing methods may not be able to capture changes and trends in the data. Therefore, new technologies and methods are needed to address these challenges in order to better manage and analyze big data.

The Structure of Big Data

The first level is theory, which is a necessary pathway to cognition and a baseline that is widely recognized and disseminated. Here from the definition of the characteristics of big data to understand the industry's overall portrayal and characterization of big data, from the discussion of the value of big data to in-depth analysis of the preciousness of big data. It provides insight into the development trend of big data, and examines the long-lasting game between people and data from the special and important perspective of big data privacy.

The second level is technology, which is the means to realize the value of big data and the cornerstone to move forward. Here the development of cloud computing, distributed processing technology, storage technology and perception technology, respectively, to illustrate the whole process of big data from collection, processing, storage to the formation of results.

The third level is practice, and practice is the ultimate value embodiment of big data. Here respectively from the Internet of big data, government big data, enterprise big data and personal big data four aspects, to depict the big data has shown a beautiful scene and the blueprint will be realized.
