When designing a solution that requires customer data from multiple external systems and ensuring it is as current as possible, consider the following:
Parallel Data Loading: Use the Load-Data Page and Connect-Wait methods to load the data in parallel. This approach improves performance by reducing the time taken to gather the required customer data since multiple data sources are queried simultaneously.
System of Record (SOR) Pattern: Employ the System of Record (SOR) data access pattern to fetch the most current customer data from the external systems directly. This ensures that the data used is up-to-date and reflects the latest information available from the source systems.
