In order to produce a complete view of a customer, a customer service(CS) application requires reference data from multiple external systems. The customer data resides on a customerinfo page in a parent case type. The data on the CustomerInfo Page is also used by some of its subcases. Sometimes, the connectors that populate the data page are slow.
Which two of the following approaches for handling the required reference data from the external systems uses the least system resources? (Choose Two.)
- Use Case Designer data propagation to copy the data to the subcases to populate the page contents.
- Use the Load-DataPage method to initiate the population of the page contents.
- Use the system of Record (SOR) data access pattern to populate the page contents.
- Use the Snapshot data access pattern to populate the page contents.
Answer(s): C,D
Explanation:
Handling reference data from external systems efficiently is crucial to minimize system resource usage.
Use the System of Record (SOR) data access pattern to populate the page contents (Answer C):
The SOR pattern ensures that the application fetches data directly from the external system when needed, rather than storing and maintaining copies of the data. This approach minimizes memory usage and keeps the data up-to-date.
Reference:
Pega's documentation on data access patterns recommends using the SOR pattern for scenarios where up-to-date data is required, and minimizing resource consumption is critical. Use the Snapshot data access pattern to populate the page contents (Answer D):
