Abstract :
Grid infrastructures enable the creation of virtual organizations for sharing distributed resources across the world with different usage or access policies, different cost models, and varying workloads and availability. Database plays an important role in fulfilling the data management requirements of Grid applications thanks to its advanced data management capability. However, when we want to integrate databases in a grid, we have to address a number of issues. One of them is the problem of database placement. In this paper, we define an economic model for the problem of database placement in Grid architecture. We propose an economic model for regulating data supply and queries. Our proposal is evaluated with OptorSim simulator. The experiments show that our proposed model results in a notable improvement for distributed query processing.
