Abstract
Content integration of web data sources is becoming increasingly important for the next generation information systems. However, all proposed solutions are faced with the same performance bottleneck: the network overhead incurred when contacting the integrated e-sites. With this demo paper we shall demonstrate the functionality of HyperHotel. HyperHotel is used for finding appropriate hotel rooms when travelling. Its novetlies are that it is designed and implemented as an internet web-hotel content integration application and that it is built on top of D.I.C.E. and Co.In.S.; a novel content integration infrastructure consisting of a domain-independent COntent INtegration System and its Data Integration Cache Engine. We?ll show how the infrastructure of D.I.C.E. and Co.In.S. can be applied and exploited in HyperHotel in order to improve the response time of complex user queries. This exemplifies the significance of this infrastructure since HyperHotel is representative of a large class of e-commerce, content integration applications.
