Data lineage in Databricks allows users to track how datasets are created, used, and modified across notebooks, jobs, queries, and tables. This end-to-end visibility helps data teams understand the full lifecycle of data within the platform. By revealing how data elements are connected, lineage supports auditing, troubleshooting, compliance, and trust in reporting.
