Abstract :
Under Grid environments, how to access a set of heterogeneous data resource in a uniformed way is a well studied subject. The two most important problems about it are: 1. how to hide the different access manners of different data resources and 2. how to map real data to virtual data which can be used by various applications. In this paper, the Data Grid virtual access and integration tool: virtual Data Center has been designed to meet these new challenges. It addresses a new paradigms and constraints which deeply impacts data access. At the same time, the virtual data access possibilities and an automated method for data resources integrating and heterogeneous data resource access are promoted.
