Data lineage is the ability to trace data from its source through every transformation to its final destination. In clinical analytics, this matters because decisions rely on data that may pass through many systems and steps. Knowing the lineage shows where a data value came from, what operations were applied (such as calculations, normalizations, or merges), and where the result ends up. This enables you to reproduce analyses, identify where data quality issues originated, and support auditability and regulatory compliance through transparent data handling. Other choices don’t fit because describing color schemes has nothing to do with data history; focusing on the network path addresses data movement rather than its full transformation history; and encryption methods relate to security, not documenting how data was transformed and where it travels.
