Today, more and more enterprises and organizations choose to depend on the Internet to realize business collaborations. For business users, they often need to gather and analyze information from multiple organizations correctly and immediately to make improvisations. Key issues behind this process are how to construct cross organizational data views in a just-in-time way and maintain the consistency between data views and sources. This paper proposes a dynamic cross-organizational view construction method fitting in with the Internet environment, called iViewer. The main ideas ofiViewer method are to encapsulate autonomous and heterogeneous data sources as a set of data services, and compose them to generate a data view in a visualized and user-friendly way. It develops a polling based view updating algorithm to maintain the consistency between the data views and sources, so that the data view can be updated as the data sources get changed. The paper discusses the principles and procedures ofiViewer in detail, and proves the effects of the iViewer method in practical fire-emergency-equipments-dispatching case, in which a cross-organizational view of fire rescuing equipment information from multiple departments is dynamically constructed for the command center.
