Data flow for sync services (left) and push services (right). The sync services retrieve data from the LDW installed in the hospital. The Patient Identity Management Service ensures that pseudonyms can be mapped to patients in ObTiMA. The push services are able to push trial data from ObTiMA either to the LDW or DWH. To translate trial data to a format compliant with HDOT the Data Translation Services are used.
