  • C. A data dictionary defines the structure and meaning of data elements, but it does not describe the processes or automation that move or transform the data.
  • D. Data lineage tracks the journey of data from its origin to its current state, detailing transformations, but a DFD provides a more comprehensive, immediate understanding of how these processes are structured and automated.
