Abstract
Grid portals are web gateways aiming at providing a pervasive and ubiquitous access in grid to computational resources, tools, instruments, datasets and metadata via standard web protocols. Moreover, they provide enhanced problem solving capabilities to deal with modern, large scale scientific and engineering problems. Data grid management systems are becoming increasingly important in the context of the recently adopted service oriented paradigm. The Grid Relational Catalog (GRelC) project is working towards ubiquitous, integrated, seamless and comprehensive grid database management solutions. This paper describes the GRelC Portal, a web based grid-enabled solution for grid-database access, management and integration built on top of the GRelC Data Access Service.
