要約(英語): The demand for navigation is rising as railway transportation services is becoming complex. Real-time data integration from multiple business systems is required for passenger-oriented navigation. Conventional mediators, real-time data integration technique which converts queries and data between business systems and applications based on their each schemes and mapping between them, can not follow expansion both of applications and business systems. In this paper, we propose a new mediator to solve the scalability problem with core-global scheme, which allows independednt mappings with each schemes of them and expresses principal components of business systems and applications. The 2 features of core-global scheme reduce effects of scheme changes on other mappings so that the mediator has scalability. Furthermore, we propose an architecture of the mediator that reduces effectivity loss of queries. We implemented a prototype and evaluated its scalability and query effectivity for an application of railway navigation.
