A Distributed Query Execution Engine in a Grid Environment

Grid is a computational environment in which applications can use multiple distributed computational resources in a safe, coordinated, efficient and transparent way. Data Integration Middleware Systems (DIMS) are originally distributed systems that can make use of Grid environments to obtain a better performance and a rational use of available resources. This work describes a Distributed Query Execution Engine (DQEE) inserted in a Grid environment for executing sub-queries and operators in a distributed and parallel way. We present an approach to obtain an efficient distributed query execution with a reduced response time by the use of the DQEE. 1
