Transformation of SPARQL queries into Cypher queries in Neo4j
Storzerová, Tereza ; Svoboda, Martin (advisor) ; Klímek, Jakub (referee)
RDF stores are still popular on the Web, although the existing RDF database management systems are not well prepared for the current data processing requirements. Usually, it is better to use one of the NoSQL systems for processing large and unstructured data instead. For many database types, the graph representation appears to be the most suitable way, with one of the popular representatives being the Neo4j system. In this thesis, we present an approach to the RDF data transformation into a graph format used by Neo4j, together with the translation of the query expressions in SPARQL to query expressions in Cypher, being the query languages used over RDF and in Neo4j, respectively. The translation of data and queries is shown on a prototype implementation and experimentally verified. 1
