Object organization on a single broadcast channel in a global information sharing environment

Abstract

Multidatabases offer practical means of managing information sharing from multiple preexisting heterogeneous databases. Furthermore, advances in computation and communication technologies allow users to access computer networks, using portable computing devices via a wireless connection, while mobile. By superimposing the mobile computing environment onto the multidatabase system, a new computing environment is attained. In this work, we concentrate on the effects of the mobile-computing environment on query processing in multidatabases. Within the broadcasting environment, the organization of the data objects along a single air channel should follow the semantic links assumed within the objects' graph. Learning from our past experiences in objects' organization on conventional storage mediums (disks), we propose a scheme for organizing objects along a single sequential broadcast channel. The proposed schemes are simulated and analyzed.
