So for example, heterogeneous data is to be gathered from different data sources, formatted, presented, and evaluated for a comprehensive cancer register. Thereby, a particular role is played by the geographical reference of the data and the possibility to spontaneously phrase and execute analyses if necessary. For this reason, OFFIS develops data-security-compliant basic technologies for the integration, quality management, and further explorative analysis of data, and converts these into concrete application projects for care research – but equally for usage outside of health care. The search in unstructured, often medial data, that plays an important role especially for personal assistance functions in daily life, becomes more important.
