This work addresses a problem of optimal query processing in heterogeneous and distributed multidatabase systems. The objective is to nd a method for opimization of global query p...
To meet users’ growing needs for accessing pre-existing heterogeneous databases, a multidatabase system (MDBS) integrating multiple databases has attracted many researchers recen...
Users have been demanding information “anytime, anywhere”. The notion of accessing diverse and autonomous information repositories with different APIs is not accepted. This ha...
In this paper, we present the design of system of databases (SyDb). We also give the design and implementation of a Java API for global querying and updates on the SyDb. The datab...
In this paper, we propose a novel deadlock resolution algorithm. In the presence of global deadlocks in a multidatabase system, this algorithm always selects an optimal set of vic...
