Dart: A framework for grid-based database resource access and discovery

Abstract

The Data Grid serves as a data management solution widely adopted by the existent data-intensive Grid applications. However, we argue that the core Grid data management demands can be better satisfied with introduction of database. In this paper, we provide a database-oriented resource management framework, which is intended to integrate database resources with the Grid infrastructure. We start by outlining the sketch of the proposed Database Grid architecture and then focus on two base-level services: the remote database access and database discovery, which we think should be firstly settled down as a necessary foundation for other high-level database services that are more application-driven. We discuss how the design principles that apply to these base-level services can adapt to the characteristics of Grid environment and how they can be nested within the OGSA paradigm. © Springer-Verlag 2004.
