Today many Data Grid applications need to manage and process a very large amount of data distributed across multiple grid nodes. Several applications often access large databases (i.e. protein data banks, in the bioinformatics field) without any data access services taking into account characteristics of either applications or data types. Such applications could improve their performance and quality of results by using efficient, cross-DBMS, specialized and ad hoc implemented data access services. The Grid Relational Catalog Project (GRelC) developed at the CACT/ISUFI Laboratory of the University of Lecce provides a grid-enabled access service for relational and not relational repositories. In this paper we propose some advanced delivery mechanisms developed within the GRelC project, showing up experimental results related to an European testbed.

Abstract
Today many Data Grid applications need to manage and process a very large amount of data distributed across multiple grid nodes. Several applications often access large databases (i.e. protein data banks, in the bioinformatics field) without any data access services taking into account characteristics of either applications or data types. Such applications could improve their performance and quality of results by using efficient, cross-DBMS, specialized and ad hoc implemented data access services. The Grid Relational Catalog Project (GRelC) developed at the CACT/ISUFI Laboratory of the University of Lecce provides a grid-enabled access service for relational and not relational repositories. In this paper we propose some advanced delivery mechanisms developed within the GRelC project, showing up experimental results related to an European testbed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
