The GRelC library: a basic pillar in the grid relational catalog architecture

Today many data grid applications need to manage and process a very large amount of data distributed across multiple grid nodes and stored in relational databases. The Grid Relational Catalog Project (GRelC) developed at the CACT/ISUFI of the University of Lecce, represents an attempt to design and deploy a grid-DBMS for the Globus Community. In this paper, after defining the grid-DBMS concept, we describe the GRelC library which is layered on top of the Globus Toolkit. The user can build client applications on top of it that can easily get access to and interact with data resources.
