Coarse-grained and fine-grained data lineage are two different levels of granularity for tracking the flow of data within an organization.

Coarse-grained data lineage provides a high-level view of the data flow, typically at the level of entire datasets or data systems. It may track the movement of data between different departments or systems within an organization, but it does not provide detailed information about individual data elements.

Fine-grained data lineage, on the other hand, provides a more detailed view of the data flow, typically at the level of individual data elements. It tracks the movement of individual data elements as they are transformed and manipulated throughout the data flow. This level of detail can be important for understanding the quality and reliability of individual data elements and identifying potential issues or errors.
