**Change Data Capture**

Change Data Capture (CDC) is a data management technique that identifies and tracks changes made to a database, enabling real-time data integration and synchronization across systems. CDC captures inserts, updates, and deletes as they occur, ensuring that downstream applications and analytics platforms always have access to the most current data without the need for full data refreshes. Widely used in data warehousing, ETL processes, and event-driven architectures, CDC helps improve efficiency, reduce latency, and maintain data consistency across distributed environments.
