How is data updated or refreshed?
Response: The underlying data in the platform is updated or refreshed using the Health Catalyst ETL engine in batches according to user-defined schedules. Some source systems are updated as often as every 10–15 minutes while the bulk of them are updated nightly. Additionally, the Catalyst Analytics Framework (SAM Engine) can be configured to refresh the analytics from the source data via either being triggered by a schedule at a certain time of day or when it detects that certain dependent data elements have been changed or refreshed. Catalyst Analytics Framework allows for many different visualization tools such as QlikView, Tableau, BusinessObjects, etc., which can be configured to run directly against the calculated analytics in the platform or to cache the analytical application or report and update on a regular schedule. That ability varies by visualization tool.
