ISO/IEC 20546:2019 Information technology – big data – overview and vocabulary

Summary

The term “big data” refers to datasets with extensive volume, velocity, variety, and variability. The big data revolution represents a fundamental shift akin to the relational model transition, driven by the inability of relational databases to manage large, often unstructured datasets. Since the mid-2000s, scaling technologies have rapidly matured, making this shift essential for modern data analysis and business considerations.
