A client has many published data sources in Tableau Server. The data sources use the same databases and tables. The client notices different…

Tableau Catalog, a part of the Tableau Data Management offering, is designed to address issues of data trust and discovery. It provides a comprehensive view of the data environment, including lineage and impact analysis. By using Tableau Catalog, the client can trace the data from the database tables to the published data sources and finally to the visualizations. This allows them to compare the metadata of the seemingly identical data sources, identify subtle differences in joins, filters, or calculated fields, and understand exactly why they produce different results. This visibility is crucial for diagnosing inconsistencies and re-establishing trust in the data.

A. Tableau Prep Conductor: This tool is used to schedule, monitor, and manage Tableau Prep flows on a server. It automates data preparation but does not analyze or compare existing published data sources.

B. Ask Data: This is a natural language query feature that allows users to explore a single data source by asking questions. It is a data consumption tool, not a governance or lineage tool.

D. Tableau Resource Monitoring Tool: This tool monitors the health and performance of the Tableau Server environment, such as hardware utilization and job performance. It does not provide insight into data content or metadata.

"Use Lineage to See the Impact of Changes": "Lineage traces your data from its original source... For data sources

you can see the upstream databases and tables... and the downstream workbooks

sheets

and dashboards that use the data source." This directly supports the use of Catalog to inspect the composition of data sources.
