Production Grids such as EGEE allow scientists and researchers using aggregated computational power and storage resources. Many Users/Virtual Organizations (VOs) e.g., bioinformatics, astrophysics, etc., need relational databases for their experiments. However, the EGEE middleware (gLite) lacks ad hoc software, and other available solutions are not currently suitable for this purpose within a gLite based environment. We present the GRelC Data Access Service, a data grid access service developed by the GRelC Team (SPACI Consortium and University of Salento) showing up how this component could be integrated within the EGEE grid. Deployment on the GILDA testbed as well as porting issues on gLite middleware are also proposed.
