Universal Containers (UC) is replacing a home grown CRM solution with Salesforce. UC has decided to migrate operational (open and active) records to Salesforce, while keeping historical records in legacy system. UC would like historical records to be available in Salesforce on an as needed basis.
Which solution should a data architect recommend to meet business requirement?
A mashup allows Salesforce to display real-time data from external systems within the Salesforce interface. This solution ensures that historical records can be accessed as needed by displaying them in Salesforce without the need to migrate all historical data. This approach is efficient and keeps historical data readily available while minimizing storage and management overhead within Salesforce.
Data virtualization is the answer
A doesn’t seem correct as there’s no need for real time. Mashup is most appropriate to host external info
What is mashup? As Praveen said, Data virtualization should be the answer, alongwith 1 time data load for active records.
Mashup is the Salesforce recommendation for an arrangement to display Salesforce-hosted data and externally hosted data. (A) is also not very clear due to the "pull records" intent.
