5 best open source data flow lineage tools

Data flow lineage is crucial for anyone handling data within organizations. Just as a navigation app provides a detailed map of roads, guiding you from your starting point to your destination while highlighting every turn and intersection, data flow lineage offers a comprehensive view of data movement and transformations throughout its lifecycle.

In essence, data flow lineage is indispensable for ensuring transparency, maintaining data quality, achieving compliance, enabling efficient troubleshooting, conducting impact analysis, and enhancing collaboration within organizations. It guides data professionals through the complexities of data management, much like a reliable navigation app guides drivers through the complexities of road travel.
