Scenario: A multinational corporation requires real-time data synchronization between its on-premises DB2 databases and its cloud-based analytics platform. Suggest a suitable integration approach and explain its benefits.
- Employ an FTP-based solution to transfer data between on-premises and cloud databases.
- Implement Change Data Capture (CDC) mechanisms to capture and propagate data changes from on-premises DB2 databases to the cloud analytics platform in real-time.
- Manually export and import data between databases periodically to ensure synchronization.
- Use a batch processing approach where data is periodically extracted from on-premises DB2 databases and loaded into the cloud analytics platform.
Implementing Change Data Capture (CDC) mechanisms allows for real-time synchronization of data changes between on-premises DB2 databases and cloud-based analytics platforms, ensuring that analytics and reporting are based on the latest data. Manual export/import or batch processing approaches introduce delays and are prone to errors, while FTP-based solutions lack the real-time capabilities required for this scenario.
