Put forward the implementation method of the semantic data be stored into the relational database. Based upon the analysis of the logic model of the semantic graph, built a storage system which consists of schema table and instance table, to enhance the integrality and agility of the storage, Describe the semantics by directed-hyper graph to simplify the semantic graph and strengthening the semantic relations, List a vertical-storage algorithm which is based on the breadth-first traversal.
