It allows organizations to minimize downtime and disruption during migration and upgrade activities.

7. Data Warehousing and Analytics: GoldenGate supports data replication for data warehousing and analytics purposes, enabling organizations to populate data warehouses and data lakes with real-time data from operational systems. This enables timely and accurate analytics, reporting, and decision support.

8. Zero-Downtime Upgrades and Maintenance: GoldenGate enables zero-downtime upgrades and maintenance for databases and applications by facilitating live migrations and updates while ensuring continuous data availability and access.

9. Change Data Capture (CDC): GoldenGate employs Change Data Capture (CDC) technology to capture data changes at the source database in real-time. It captures inserts, updates, and deletes made to database tables and replicates them to target systems for synchronization.

10. Monitoring and Management: GoldenGate provides monitoring and management tools for administrators to monitor replication processes, track performance metrics, and troubleshoot issues. It offers graphical user interfaces, command-line tools, and APIs for managing and administering GoldenGate environments.
