Data quality was one of the biggest and most important issues linking all the topics mentioned. This was made particu­larly clear by the fact that almost all of the presen­tations and discussions illus­trated the importance of data quality. The speakers’ and participants’ opinions were divided on only one point: where should the starting point for improving data quality be located? While some recommended a top-down approach in which the push has to come from management, the others favoured a bottom-up approach with the momentum coming from the specialist division and the users. Our product Q-THOR fits perfectly into the presentation ‘Data Quality as a Success Factor in Times of Explosive Data Volumes’.
