The main goal of data management in the second funding period of the DZL is the development and implementation of a central data repository (DWH). Ensuring the sustainable use of the data in the DWH is a top priority. Currently, the integrated data is not yet completed and consistent. The aim of our research project is the improved use of the data (e.g. for the preparation for new innovative studies). As part of our project, we intend to find inconsistencies, make data quality measurable, draw up suggestions to improve data-processing methods, and provide the general public with an overview of the data pool in visual form.
