Abstract:
Grid computing allows to integrate resources (computers, networks and storage devices) geographically dispersed to obtain a computational infrastructure very appropriate for the resolution of complex problems of the science, engineering, industry and society. In this kind of environments, the access to the information continues being a problem. Currently there are a great interest in develop technologies to integrate storage resources in grid environments. The objective of these technologies is to provide an infrastructure for data grids environments. This kind of infrastructure facilitates a logical view of heterogeneous distributed data resources that are shared between autonomous administrative domains, and provides a location independent logical namespace. The objective of this tutorial is to introduce the data grid technologies, covering introduction, existing technologies, open research issues, and demonstrations if possible.
