What are the five characteristics of Internet big data?

Big data as a whole is divided into four characteristics.

First, a lot.

The unit of measurement is PB, and there are many storage contents.

Second, high speed.

Big data needs to be timely and fast in terms of acquisition speed and analysis speed. Ensure that more people receive the information in a short time.

Third, diversity.

The source of data is obtained from various channels, including text data, picture data, video data and so on. So the data is varied.

Fourth, value.

Big data not only has its own information value, but also has commercial value. Big data is structurally divided into structured, semi-structured and unstructured. Structured simply, it is a database, which is expressed and realized by two-dimensional tabular logic. Unstructured means that the data structure is irregular or incomplete, and there is no predefined data model. Most of the data generated by human beings are unstructured data.
