This book constitutes the refereed proceedings of the 8th International Workshop on Databases in Networked Information Systems, DNIS 2013, held in Aizu-Wakamatsu, Japan in March 2013. The 22 revised full papers presented were carefully reviewed and selected for inclusion in the book. The workshop generally puts the main focus on data semantics and infrastructure for information management and interchange. The papers are organized in topical sections on cloud-based database systems; information and knowledge management; information extraction from data resources; bio-medical information management; and networked information systems: infrastructure.

This book constitutes the refereed proceedings of the 7th International Workshop on Databases in Networked Information Systems, DNIS 2011, held in Aizu-Wakamatsu, Japan in December 2011. The 18 revised full papers presented together with 6 invited talks and 1 keynote lecture were carefully reviewed and selected for inclusion in the book. The workshop generally puts the main focus on data semantics and infrastructure for information management and interchange. The papers are organized in topical sections on cloud computing; access to information resources; information and knowledge management; bio-medical information management; information extraction from data resources; geo-spatial decision making; networked information systems: infrastructure.

Large-scale information systems in public utility services depend on computing infrastructure. Many research e?orts are being made in related areas, such as mobile computing, cloud computing, sensor networks, high-level user interfaces and information accesses by Web users. Government agencies in many countries plan to launch facilities in education, health-care and information support as a part of e-government initiative. In this context, information interchange m- agement has become an active research ?eld. A number of new opportunities have evolved in design and modeling based on the new computing needs of the users. Database systems play a centralrole in supporting networkedinformation systems for access and storage management aspects. The 6thinternationalworkshoponDatabasesin NetworkedInformationS- tems (DNIS) 2010 was held during March 29-31, 2010 at University of Aizu in Japan. The workshop program included research contributions and invited c- tributions. A view of research activity in information interchange management and related research issues was provided by the sessions on related topics. The keynoteaddresswascontributedbyDivyakantAgrawal. Theworkshopsessionon "NetworkedInformationSystems:Infrastructure"had invitedpapersbyHarumi KunoandMaluCastellanos. Thesessionon"AccessestoInformationResources" had an invited contribution from Joachim Biskup. The following section on "Information and Knowledge Management Systems" included invited contri- tions from Toyoaki Nishida and Tetsuo Kinoshita. The session on "Information Extraction from Data Resources" included the invited contribution of Polepalli Krishna Reddy. The section on "Geospatial Decision Making" comprised c- tributions by Cyrus Shahabi and Yoshiharu Ishikawa. We would like to thank the members of the Program Committee for their support and all authors who contributed to DNIS 2010.
