The Semantic Web is an extension of the traditional Web aimed at facilitating information and knowledge sharing. In this context, RDF has been conceived as a means for a simple representation of any kind of data and metadata, according to a graph-based, lightweight model and a straight XML serialization. Although RDF has the advantage of being general and easy to use, it cannot be adopted as a storage model, since it can be easily shown that even simple data management operations yield serious performance problems. In this paper, we present a novel approach for storing, managing and processing RDF data in an effective and efficient way. The approach is based on a logical organization that is particularly suited for RDF constructs, but it can be easily extended to other RDF-based languages, such as OWL.
