Abstract

'This article introduces the data integration and consolidation process of the research data base of the Institute for Employment Research. The data are process generated data and stem from various, autonomous administrative processes. This fact implies that there are manifold inconsistencies between the data from the different data sources. This opens up the methodological problem of a successful consolidation of inconsistencies. Two contrarian strategies to handle this methodological problem are discussed and the solution in the IAB-data base is presented.' (author's abstract)
