Introduction

Regulators demand understanding of data flow through analytics systems: which raw data feeds which reports? Data lineage—tracking data transformations from source to output—is complex at scale. Visual dashboards represent lineage, enabling compliance teams and auditors to quickly understand data flows.

Lineage Tracking

Capture data lineage automatically: which data sources feed which transformations, which models use which features, which reports output which metrics. Use metadata tracking in data lakes and ML pipelines. Reconstruct complete lineage graphs.

Visualization

Interactive dashboards show data lineage as directed graphs: sources (top) → transformations (middle) → outputs (bottom). Click on nodes for details: data schema, transformation logic, access logs. Search functionality finds paths between sources and outputs. Filter by compliance domain (trading, risk, etc.).

Conclusion

Data lineage visualization dramatically simplifies compliance documentation and audit response times.
