Caching Objects from Heterogeneous Information Sources

Information exchange has shown a rapid growth due to Internet expansion and has altered the structure of information sources worldwide. Structured and semistructured data are stored in various heterogeneous information sources and, thus, tools have been developed for facilitating their rapid integration. The goal of this paper is to extend the integration process by the introduction of caching techniques to the client environment, in order to decrease access time to objects distributed over various information sources
