Data Lineage and Data Governance in Tableau

Updated: Aug 16, 2019

Why is Data Lineage Required?

Enterprise data passes through multiple phases during the Tableau life-cycle. There are multiple sources, structures, transformations and movements that data has to go through at various stages. As business complexities increase, the data - dependency and business risk of making even a small error in data reconciliation across various stages have a huge effect on the business outcomes. At times it is extremely difficult to pinpoint the stage, or action causing the error.

Data Lineage answers questions like, “Where did the data come from?” or “How did we arrive at this number?” etc.

Data lineage works as a snapshot of the data flow inside the Tableau workbook. It captures the data from Source to visualization along with its various intermediate stages including Data source filters, logic applied in calculated fields, Table calculations, used parameters etc.

Where will it be used?

This knowledge about data can be helpful for better data governance, data quality, master data management and overall metadata management.

Data Lineage helps in knowing the original source of the data and understanding what happens to the data as it finally flows into a report. This helps in better management of data, improving the overall business intelligence infrastructure and ultimately to better decision making.
