| Abstract(in English) | Integration of heterogeneous information sources has been one of important data engineering rescarch issues. Various types of information sources are available today. They include dissemination-based information sources, which actively and autonomously deliver information from server to users. We have been developing a mediator/wrapper-based information integration system, in which we employ ECA rules to define new information delivery services integrating multiple existing dissemination-based information sources. In this system, ECA rules are derived from the relatinal algebra specified by the user. If we utilize constraints on information sources, such as information delivery schedule, system can derive more appropriate ECA rules and more strictly check consistency of requirements. In this paper, we propose a scheme to process information integration requirements using constraints on dissemination-based information sources. |
