- Abstract
- OGSA-DQP is A Service-Based Distributed Query Processing system in the Grid. It is concerned with providing a an approach to deliver High level Data Access and Integration services which are needed if data-intensive distributed applications running on heterogeneous platforms are to benefit from the Grid. It provides a uniform virtual data view above multiple relational database in the grid, Grid users can issue their queries based on the virtual view. Firstly, the architecture of OGSA-DQP was described. Then, the internal query and optimization mechanism of OGSA-DQP was analyzed. The query performance was evaluated for finding the bottlenecks of query performance and improving the query response time.
