With the advancement of technologies in wireless communication and computer down-sizing, it becomes possible to access a global network using handy terminals which are equipped with wireless communication facilities. In such a mobile computing environment, data management is one of the primary objectives of effective computer used. However, since conventional distributed data management technologies assume that servers and clients are fixed at certain locations in a network, they do not provide any tools to construct advanced applications which make full use of dynamically changing information in such an environment. In this paper, in order to incorperate data distributed over mobile computing environment, we propose a dynamic data integration mechanism called MobiView which is an enhanced view mechanism of a conventional database system. In MobiView, we introduce four methods for database indication without using conventional host name or its local name: host-specified, cell-specified, location-dependent, and MobiView-oriented, through which we discuss how to handle both mobile database servers and mobile database clients.
