What is data lineage and why is it important in Clarity modeling?

• A. Data lineage traces data from source to destination through transformations, enabling impact analysis, governance, and trust.
• B. Data lineage is a naming convention for tables.
• C. Data lineage only concerns data types.
• D. Data lineage is the process of backing up data.

Answer: (A)

In Clarity modeling, data lineage describes how data travels from its original sources, through all transformations, to its final use in analyses and reports. This visibility shows exactly how a value is produced, what steps modify it, and which downstream models or dashboards depend on it. That understanding is powerful for impact analysis: when you consider changing a source or a transformation, you can trace all affected downstream objects and plan accordingly. It also supports governance and trust by documenting data provenance and the transformations applied, helping with accountability, reproducibility, and data quality. Additionally, it makes debugging and change management easier because you can follow the precise path the data took and see where things may have gone awry. The other ideas don’t fit because data lineage isn’t simply a naming convention for tables, nor is it limited to data types, and it isn’t about backing up data.
