    "description": "A centralized master data management hub that maintains golden records\nfor customers, products, suppliers, and organizational hierarchies\nacross the enterprise. FastAPI exposes CRUD and match-merge APIs with\nconfigurable survivorship rules for conflict resolution. PostgreSQL\nstores the master records with full change history and lineage tracking.\nRabbitMQ distributes change events to downstream consumers ensuring\neventual consistency across systems. Apache Airflow orchestrates batch\ndata quality jobs, deduplication pipelines, and cross-reference\nreconciliation. The tradeoff is the political complexity of data\nownership governance and the computational cost of probabilistic\nmatching at scale.\n",
