Design of a Master Data Quality Control System for Power Enterprises Based on Data Lineage

A master data quality control system based on data lineage is proposed for power enterprises. Field-level lineage is built by combining static parsing, runtime events, and interface registration, and quality rules are bound to lineage nodes. Quality inspection, root-cause tracing, impact analysis, work-order handling, and version auditing form a closed loop. Scenario walkthroughs show that the system can locate anomaly sources, identify propagation scope, and verify recovery, providing an implementable framework for master data governance.
