Dart-Fas: Federated Access Service On Database Grid

The emergence of a service-oriented view of computation and data resources on the grid raises the question as to how database resources can best be deployed or adapted for use and management in Grid. Several proposals have been made for the development of Grid-enabled database services. However, there are few service orchestration frameworks for constructing sophisticated higher-level services that allow database dynamic federation and distributed transaction to take place within a Database Virtual Organization. As the phase 11 of DartGrid we propose DART-FAS, a service orchestration focusing on the construction of dynamic federation and federated access service in Database Grid. This paper will discuss the architecture, core components and primary processes of DART-FAS.
