In this paper we propose an approach to the storage, query, manipulation and inference of large RDF(S) data on top of relational databases. Specifically, RDF(S) inference is done on the database in advance instead of on the fly, so that the query efficiency is maximized. To reduce the cost of inference, two inference modes, the batch mode and the incremental mode, are provided for different scenarios. In both modes, optimized strategies are applied for efficiency purpose. In order to support efficient query and inference on the database, the storage schema is also specially designed. In addition, a powerful RDF(S) query and manipulation language RQML is provided for easy and uniform data access in a declarative way. Finally, we evaluate and report the performance on both query and inference of our approach. Experiments show that our approach achieves encouraging performance in million-scale real data.
