Information systems in transportation, health-care and public utility services depend on computing infrastructure. Many research e?orts are being made in related areas, such as wireless computing, data warehousing, stream proce- ing, text-based computing, and information accesse by Web users. Government agencies in many countries plan to launch facilities in education, health-care and information support as e-government initiatives. In this context, Web c- tent and query interface adaptation for ubiquitous access to data resources has become an active research ?eld. A number of new opportunities have evolved in design and modeling based on the new computing needs of users. Database s- tems play a central role in supporting networked information systems for access and storage management aspects. The?fthinternationalworkshoponDatabasesinNetworkedInformationS- tems (DNIS 2007) was held on October 17–19, 2007 at the University of Aizu in Japan. The workshop program included research contributions and invited c- tributions. A view of research activity in geospatial decision making and related research issues was provided by the session on this topic. The invited talk was given by Dr. Cyrus Shahabi. The workshop session on Web Data Management Systems included invitedpapersby Prof.MasahitoHirakawaandDr.Gao Cong. The sessions on Networked Information Systems included the invited contri- tions by Prof. Divyakant Agrawal and Prof. Krithi Ramamritham. I would like to thank the members of the Program Committee for their support and all the authors who submitted their papers to DNIS 2007.
