AS ISO/IEC 20547.3:2022 identically adopts ISO/IEC 20547 3:2020 which specifies the big data reference architecture (BDRA). This architecture includes concepts and architectural views through a user view defining roles/sub-roles, their relationships, and types of activities within a big data ecosystem and a functional view defining the architectural layers and the classes of functional components within those layers that implement the activities of the roles/sub-roles within the user view.
