A company has a document that includes the names of key metrics and the standard for how those metrics are calculated company-wide. Which of the following describes this documentation?

A data dictionary is a centralized repository of information about data, including definitions, data types, format, relationships, and importantly, the business rules and calculation methods for key metrics. This ensures consistent understanding and use of data across the organization.

A data explainability report focuses on understanding how a model or algorithm arrived at a particular output, not on defining metrics and their calculations.

Data lineage tracks the origin, transformations, and movement of data over its lifecycle, rather than defining the metrics themselves or their calculation standards.

A data flow diagram (DFD) visually represents the flow of data within a system, showing inputs, processes, and outputs, not the definitions or calculation standards of individual metrics.
