Most data generated by the Internet industry is structured data, amounting to 80% of total data.

The statement is factually incorrect. The overwhelming majority of data generated by the Internet industry and modern enterprises is unstructured data, not structured data. Unstructured data includes emails, social media posts, videos, images, audio files, and documents. Industry analysis and academic literature consistently estimate that unstructured data comprises approximately 80% of all data and is growing at a much faster rate than structured data. Structured data, which is highly organized and fits into relational databases, represents a much smaller fraction of the total data volume.

The statement is false because it reverses the common and well-documented ratio of structured to unstructured data. It is unstructured data that accounts for the 80% majority, while structured data constitutes the remaining minority.

It states that unstructured data, such as videos, images, and documents, accounts for over 80% of the total data volume in the big data era. (Reference: HCIA-Storage V5.0 Training Material, Chapter 1: Big Data and Storage Technology Trends, Section 1.1.2 Data Types).

In the section discussing the "Variety" characteristic of Big Data, the authors state, "A wide variety of data types and formats need to be processed and managed... It is estimated that more than 80% of all data today is unstructured." (Page 138, Section 2.1. Characteristics of Big Data). DOI: https://doi.org/10.1016/j.ijinfomgt.2014.10.007.

3. University of California, Berkeley, School of Information. Courseware for "INFO 201: Research Design and Analysis for Information." Lecture materials on "Big Data" frequently cite the industry standard statistic that 80-90% of the world's data is unstructured and that this proportion is increasing due to the proliferation of social media, IoT devices, and multimedia content.
