Daily Term: Data Lineage

Data Lineage

Data Lineage tracks the origin, movement, and transformation of data through a system, providing a clear audit trail. For example, it can show how raw sales data was cleaned, aggregated, and loaded into a data warehouse. Data lineage is crucial for debugging, ensuring data quality, and meeting regulatory requirements, but it can be challenging to implement in complex systems with many transformations.
