SAP Data Services is SAP's platform for data integration, data quality, data profiling and text data processing. It extracts, transforms, cleanses and loads structured and unstructured data between source and target systems. Typical uses are loading SAP Business Warehouse in batch and data migrations, for example to SAP S/4HANA. It is self-managed server software installed on Windows or UNIX/Linux, not a SaaS service.
SAP Data Services is developed by SAP SE, headquartered in Walldorf, Germany. It grew out of BusinessObjects Data Integrator, which SAP gained when it acquired Business Objects in 2007. Because customers install it on their own servers, data location and operation are under their control. For a European organisation, this combines a European vendor with infrastructure it chooses itself, although hosting on a non-European cloud would still bring that provider's jurisdiction into play.
