Program and Proceedings
The DIVO 2004 workshop is exploring the use of database technology in virtual organizations. A virtual organization is a dynamically formed coalition of parties from different home organizations who want to cooperate with one another to reach a common goal, often within a very short time frame. Virtual organizations arise in business, government, educational, and military contexts, often in response to opportunities or challenges that cannot be anticipated in advance and require a rapid response. Virtual organizations have information sharing needs that cross traditional organizational boundaries and require rapid deployment; they cannot be fully satisfied using traditional database technology.
The DIVO workshop is formulated with three goals in mind: to serve as a forum for members of the database research community to learn about the needs of particular kinds of virtual organizations, and to serve as a forum for presenting research results and position papers that show how information technology can address the needs of virtual organizations. To this end, the DIVO workshop will focus on a particular database need found in virtual organizations, and highlight the requirements found in a particular type of virtual organization. The technical focus for DIVO 2004 is on information integration for virtual organizations, and the application area is crisis management.

Technical Focus: Information Integration for Virtual Organizations
relevant to a virtual organization is likely to reside in a variety of
sources, such as in-field sensors, remote sensing systems, video, human
reports, in-house and external databases, GIS sources, etc. These
heterogeneous information sources are likely to belong to separate
autonomous organizations, and the organizations may or may not trust one
another. The objective of information integration research for virtual
organizations is to provide seamless access to integrated multimodal
data to users in the format most useful for their task and in the time
frame that they require, while still adhering to the information sharing
policies of the data owners.

Application Area: Crisis Management
crisis situations that arise due to natural or man-made causes is a
critical challenge for modern society. Crisis
management refers to the activities encompassing the immediate
response to a disaster event (damage assessment, response needs
assessment, response prioritization), recovery efforts, mitigation, and
preparedness efforts to reduce the impact of possible future crises,
such as earthquakes, hurricanes, tornadoes, fires, floods, attacks on
physical, computing, or communication infrastructures, biological and
chemical attacks, and nuclear emergencies. For example, in the case of
an earthquake, response activities include coordination and mobilization
of rescue operations, resource and logistic planning (e.g., triage,
medical care, food, water, shelter), evacuation planning (of people,
machinery, and property), situation monitoring, and timely information
dissemination to citizens, news media, agencies, and hospitals. In each
of these steps, timely access to the right information by the right
person/agency/team at the required level of detail is key to the success
of the operation. One fundamental cause for high response latency is the
limitations of existing information, computation, and communication
infrastructures in collecting, processing, interpreting, integrating,
prioritizing, and disseminating large amounts of diverse types of
unstructured information over potentially damaged, unreliable, insecure,
and partially available network and communication infrastructures.
Another impediment is the lack of sophisticated techniques for logistics
and resource planning, and decision making in the presence of unreliable
and imprecise information.
