Supporting end users in analyzing multiple data sources

The analysis of data from multiple sources promises rich insights into complex phenomena. However, such an analysis requires data integration, which remains difficult for users without programming skills. In order to enable those users to perform ad-hoc data analysis of multiple data sources, we are researching their cognitive support needs and developing tools that provide appropriate cognitive support for this task. As part of this, we are exploring a widget-centric data integration and analysis approach.
