Figure 1 represents the process of data-transfer from the emergency department to the local data warehouse.

Figure 2 depicts the transfer of the CDA-documents and hereby generated Logs and Status reports in detail. The error reports of Import-Logs and Status information are sent to broker and DWH-manager immediately. The CDA-filing can be optionally activated. The CDAs remain in the local AKTIN-Server and can only be accessed with an appropriate admission for the diagnosis-purposes. Due to the fact that only generated as well as sent documents can be logged by the AKTIN-Infrastructure and no ID can be processed, there is no full tracking. From that point, the KIS-Export or CDA Sender must conduct a Log that contains the information if all cases are sent successfully. (http-Status 200/201).
