The basic characteristics of data are as follows:

1. Volume, the size of the data that determines the value and potential information of the data under consideration;

2. Variety, the diversity of data types;

3. Velocity, the speed of obtaining data;

4, Variability, which hinders the process of processing and managing data efficiently;

5, Authenticity, the quality of the data;

6, Complexity, the huge volume of data and the multiple channels of sources;

7, Value, the rational use of Big Data to create high value.

Extended information:

Data (data) is a term that refers to the amount of data that is available in the market. p>Data (data) is the result of facts or observations, a logical generalization of objective things, and unprocessed raw material used to represent objective things.

Data can be continuous values, such as sounds and images, called analog data, or discrete, such as symbols and text, called digital data.

Structure of Big Data:

Big data includes structured, semi-structured and unstructured data, and unstructured data is increasingly becoming a major part of data. According to IDC, 80% of data in the enterprise is unstructured, and this data is growing exponentially by 60% every year.

Big data is the development of the Internet to the present stage of a kind of appearance or characteristics, there is no need to myth it or keep in awe of it, in the cloud computing as the representative of the technological innovation of the curtain of the lining, these originally seem difficult to collect and use the data began to be easy to use, through the continuous innovation of all walks of life, big data will gradually create more value for human beings.

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 y analyze the preciousness of big data; insight into the development trend of big data; and from the privacy of big data, a special and important perspective to look at the long-lasting game between people and data.
