Let's discuss the system design of your existing Salesforce integration with a Java backend. Could you please elaborate on the architecture, including specific details about data flow, integration patterns, and technologies used? For example, walk me through a scenario where a new account is created in Salesforce, and how that information propagates to your Java backend system. What mechanisms are in place for real-time updates versus batch processing? How do you handle data transformations and ensure data integrity across both systems? What are the key considerations for scalability, security, and fault tolerance in your design? Finally, describe the monitoring and alerting mechanisms you have implemented to ensure the integration is running smoothly and to quickly identify and address any issues that may arise. Provide details on the error handling strategies employed to prevent data loss or corruption in the event of failures.
