Data Warehouses and Business Intelligence for Social Sciences. Aims and Possibilities of a Data Warehouse within the National Educational Panel Study (NEPS) in Germany

Presenter 1
David Schiller
University of Bamberg, National Educational Panel Study (NEPS)

The National Educational Panel Study NEPS (which is supported by the German Federal Ministry of Education and Research) was established in 2008. Based on a multicohort sequence design 60,000 target persons within six starting cohorts will be followed through their life course. The main aims of the NEPS are to increase the knowledge about the development of competencies, the impact of learning environments, social inequality and educational decisions, educational acquisition with migration background, and the returns of education. The NEPS data will be stored in a data warehouse. A data warehouse and the tools of Business Intelligence provide a higher level of flexibility than ordinary file servers or conventional transactional databases. Some of these additional opportunities are: Easier access to the data, data can be offered in different dimensions for various statistical packages (such as Stata), data from different sources can be matched, the user can build his/her own private use files (e. g., by selecting variables depending on the personal needs via a shopping basket), results and new computed variables can be easily stored within the data warehouse for further use by different users, the statistical power within the data warehouse can be used without an additional statistical software and even new solutions of disclosure control and anonymization techniques can be integrated.
