Salesforce Integration-Architect Exam With Confidence Using Practice Dumps

Middleware should coordinate request delivery and payment processing, and Payment System should process a payment request only once. This solution ensures that each payment request is delivered to the Payment System in a reliable and consistent manner,and avoids duplicate or conflicting updates to the same Payment Request record. Middleware can act as a mediator between the Data Entry Point and the Payment System, and implement logic to handle errors, retries, and acknowledgments. Payment System can usethe globally unique identifier to check if a payment request has already been processed, and avoid processing it again.

The system types, the error handling mechanisms, and the data volume and processing volume are three constraints and pain-points that an integration architect should consider when choosingthe integration pattern/mechanism. The system types determine what kind of interfaces and protocols are available or required for the integration, such as APIs, file systems, email, etc. The error handling mechanisms ensure that the integration can handleany failures or exceptions gracefully and provide appropriate logging and notification.The data volume and processing volume affect the performance and scalability of the integration, as well as the choice of synchronous or asynchronous methods.
