This book constitutes the thoroughly refereed joint post-proceedings of nine workshops held as part of the 10th International Conference on Extending Database Technology, EDBT 2006, held in Munich, Germany in March 2006.

The 70 revised full papers presented were selected from numerous submissions during two rounds of reviewing and revision. In accordance with the topical focus of the respective workshops, the papers are organized in sections on database technology in general (EDBT PhD Workshop), database technologies for handling XML information on the Web (DataX 2006), inconsistency and incompleteness in databases (IIDB 2006), information integration in healthcare (IIHA 2006), semantics of sequence and time dependent data (ICSNW 2006), query languages and query processing (QLQP 2006), pervasive information management (PIM 2006), pattern representation and management (PaRMa 2006), and reactivity on the Web.

This volume comprises papers from the following ?ve workshops that were part of the complete program for the International Conference on Extending Database Technology (EDBT) held in Heraklion, Greece, March 2004: * ICDE/EDBT Joint Ph. D. Workshop (PhD) * Database Technologies for Handling XML-information on the Web (DataX) * Pervasive Information Management (PIM) * Peer-to-Peer Computing and Databases (P2P&DB) * Clustering Information Over the Web (ClustWeb) Together, the ?ve workshops featured 61 high-quality papers selected from appr- imately 180 submissions. It was, therefore, dif?cult to decide on the papers that were to beacceptedforpresentation. Webelievethattheacceptedpaperssubstantiallycontribute to their particular ?elds of research. The workshops were an excellent basis for intense and highly fruitful discussions. The quality and quantity of papers show that the areas of interest for the workshops are highly active. A large number of excellent researchers are working on the aforementioned ?elds producing research output that is not only of interest for other researchers but also for industry. The organizers and participants of the workshops were highly satis?ed with the output. The high quality of the presenters and workshop participants contributed to the success of each workshop. The amazing environment of Heraklion and the location of the EDBT conference also contributed to the overall success. Last, but not least, our sincere thanks to the conference organizers - the organizing team was always willing to help and if there were things that did not work, assistance was quickly available.
