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):
Explanation: 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.
[: 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):, Explanation: The Snapshot pattern captures a specific state of data at a point in time. This approach is useful for reference data that does not change frequently, reducing the need for repeated data fetching and conserving system resources., Reference: According to Pega’s best practices for data management, the Snapshot pattern is ideal for data that remains relatively static, helping to optimize resource utilizatio, , , , , ]
