Data lineage and provenance concepts
Data lineage and provenance refer to the tracking and documentation of data’s origins, movements, and transformations throughout its lifecycle. Data lineage maps the flow of data from source to destination, showing how it changes over time. Provenance focuses on the historical record of data, detailing where it came from, how it was processed, and by whom. Together, they ensure data transparency, reliability, and compliance in data management processes.

💡 Key Takeaways
- Distinguish data lineage from provenance and why both matter for AI risk governance.
- Explain how data lineage tracks data flow from source to destination, including transformations over time.
- Describe data provenance as the historical record of data origins, versions, and custody.
- Identify practical methods to capture lineage and provenance and how they support auditing, compliance, and model debugging.
❓ Frequently Asked Questions
What is data lineage?
Data lineage tracks the origins, movements, and transformations of data through its lifecycle, showing where data comes from and how it changes as it flows from source to destination.
What is data provenance?
Data provenance is the historical record of a data item, including its sources, processing steps, and context, used to understand how the data was produced.
How are data lineage and data provenance different?
Data lineage focuses on the path and transformations data undergoes from source to endpoint, while provenance emphasizes the broader history, origin, and context that establish trust in the data.
Why is data lineage important for AI risk management?
It supports transparency, reproducibility, data quality assessment, bias detection, and regulatory compliance by revealing how data was collected, processed, and modified for AI models.
What are common components of data lineage?
Source systems, destination targets, transformation steps, timestamps, ownership, and metadata that describe data quality and lineage relationships.
