Abstract

Database services are tightly connected to network nodes, in present distributed query processing. We believe that dynamic changes of data and services environment are unpreventable. Currently, moving services to other locations, while continuing operations’ execution without notifying their clients (service migration), is not supported. We analyze requirements for transparent migration of database services, in this paper. We also sketch a solution based on so called migration agents and middle layer for abstract network communication. We emphasize the importance of the research in the wide area heterogeneous networks, Grid databases and mobile solutions, in the conclusion.
