What term describes the complete infrastructure that an organization uses to manage its data?

The term that best describes the complete infrastructure that an organization uses to manage its data is "data ecosystem." A data ecosystem encompasses not only the physical infrastructure and technological components, such as databases and data processing tools, but also the processes, people, and policies involved in the collection, storage, analysis, and governance of data.

This broad and holistic view of how various elements interact and function together to support data-driven initiatives is what sets the data ecosystem apart. It includes everything from the hardware and software used to process data, to the cultural aspects, such as how data is valued and utilized within the organization.

In contrast, while "data pipeline" refers specifically to the series of processes that move data from one point to another, and "data architecture" focuses on the structure and organization of data systems, these terms do not capture the entire scope represented by the concept of a data ecosystem. "Data framework" generally pertains to the guidelines or methodologies that inform data management practices but lacks the comprehensive nature of the ecosystem concept.
