Moflex transaction model for mobile heterogeneous multidatabase systems

Users on mobile hosts can access information from heterogeneous multidatabase systems by mobile transactions via wireless communication. Hence, a mobile transaction model should include not only features for heterogeneous multidatabase systems but also those for a mobile computing environment. In this paper, we propose a mobile transaction model to support the requirements of mobile heterogeneous multidatabase systems. The proposed Moflex (Mobile flexible) transaction model is able to support the management of mobility, heterogeniety and flexibility in the definition and execution of mobile transactions. Hence, the Moflex transaction model can be suitable for mobile heterogeneous multidatabase systems that have low power capability, low bandwidth and a high possibility of communication failure.
