RDF Date Storage Scheme Based on Graph Database

The structure can be directly mapped to the RDF model, and RDF data can be stored in the graph database. There is no need to rebuild the RDF graph to query the semantic information data of RDF. Based on the RDF data storage Scheme of graph database, the research status of RDF data storage and the transformation of SPARQL query language into Cypher graph query language are discussed emphatically. It is verified by experiments that the Neo4j graph database can further improve the query efficiency while satisfying the query of RDF graph data.
