“…In this way, the computation and the communication costs overlap resulting in decreased query total response time. Note that mitigating the impact of high data transmission in service based systems is an ongoing activity already yielding significant results (see [14,15,35]) from which our unifying architectural proposal can benefit.…”

a b s t r a c tData Grids rely on the coordinated sharing of and interaction across multiple autonomous database management systems. They provide transparent access to heterogeneous and autonomous data resources stored on Grid nodes. Data sharing tools for Grids must include both distributed query processing and data integration functionality. This paper presents the implementation of a data sharing system that (i) is tailored to data Grids, (ii) supports well established and widely spread relational DBMSs, and (iii) adopts a hybrid architecture by relying on a peer model for query reformulation to retrieve semantically equivalent expressions, and on a wrapper-mediator integration model for accessing and querying distributed data sources. The system builds upon the infrastructure provided by the OGSA-DQP distributed query processor and the XMAP query reformulation algorithm. The paper discusses the implementation methodology, and presents empirical evaluation results.

“…Furthermore, as data resources are accessed via OGSA-DAI, which in turn is designed to be extensible with repect to the sorts of data resource accessed (e.g. [46]), OGSA-DQP has been able to be extended to support different categories of data resource, including XML data resources and web-based data resources [53]. The focus on this paper has been narrower, with a view to detailing the stable features that form the public release of OGSA-DQP, and that have served as a starting point for these more preliminary investigations.…”

Service-based approaches are rising to prominence because of their potential to meet the requirements for distributed application development in e-business and e-science. The emergence of a service-oriented view of hardware and software resources raises the question as to how database management systems and technologies can best be deployed or adapted for use in such an environment. This paper explores one aspect of service-based computing and data management, viz., how to integrate query processing technology with a service-based architecture suitable for a Grid environment. The paper addresses this by describing in detail the design and implementation of a service-based distributed query processor. The query processor is service-based in two orthogonal senses: firstly, it supports querying over data storage and analysis resources that are made available as services, and, secondly, its internal architecture factors out as services the functionalities related to the construction and execution of distributed query plans. The resulting system both provides a declarative approach to service orchestration, and demonstrates how query processing can benefit from a service-based architecture. As well as describing and motivating the architecture used, the paper also describes usage scenarios, and, using a bioinformatics application, presents performance results that benchmark the system and illustrate the benefits provided by the service-based architecture.
