How does Qlik Sense manage data refreshes?

Qlik Sense manages data refreshes by utilizing scheduled reloads or manual triggers, which allows for flexibility in how and when data is updated within the application. This capability enables users to set predefined schedules for data reloads to occur at appropriate times, ensuring that data remains current without requiring constant intervention. Additionally, users can manually trigger data refreshes whenever needed, providing control over the timing of data updates, especially in dynamic environments where data changes frequently.

The option of automatic triggers only lacks the flexibility provided by manual loading. Requiring user confirmation before every refresh would be disruptive and inefficient, impacting user experience by imposing unnecessary checks. Lastly, relying solely on real-time streaming does not accommodate all use cases, especially in scenarios where data needs to be refreshed on a set schedule or when manual intervention is desirable before initiating a data load. Thus, the combination of scheduled and manual triggers provides a comprehensive approach to managing data refreshes in Qlik Sense.
