Querying Rdf Data Stored in Dbms: Sparql to Sql Conversion
This paper discusses the design and implementation of a tool for SPARQL to SQL conversion. The converter receives a SPARQL query which is then parsed and analyzed. All three current approaches to storing RDF data in RDMS (triple store, property tables, and vertical partitioning) are supported in this paper. Depending on the tool's configuration one of these methods is chosen and a proper SQL qu...
متن کاملQuest: Effcient SPARQL-to-SQL for RDF and OWL
Motivation. One of the most important uses of semantic technology is that of Ontology Based Data Access (OBDA), where the objective is to use shared vocabularies and ontologies as means to access data living in possibly disperse and heterogenous data sources (e.g., relational DBMS, XML databases, spreadsheets, etc.) Today this task often involves an ETL process in which the data is (E)xtracted ...
متن کاملScalable SPARQL Querying of Large RDF Graphs
The generation of RDF data has accelerated to the point where many data sets need to be partitioned across multiple machines in order to achieve reasonable performance when querying the data. Although tremendous progress has been made in the Semantic Web community for achieving high performance data management on a single node, current solutions that allow the data to be partitioned across mult...
متن کاملQuerying Distributed RDF Data Sources with SPARQL
Integrated access to multiple distributed and autonomous RDF data sources is a key challenge for many semantic web applications. As a reaction to this challenge, SPARQL, the W3C Recommendation for an RDF query language, supports querying of multiple RDF graphs. However, the current standard does not provide transparent query federation, which makes query formulation hard and lengthy. Furthermor...
متن کاملS2RDF: RDF Querying with SPARQL on Spark
RDF has become very popular for semantic data publishing due to its flexible and universal graph-like data model. Thus, the ever-increasing size of RDF data collections raises the need for scalable distributed approaches. We endorse the usage of existing infrastructures for Big Data processing like Hadoop for this purpose. Yet, SPARQL query performance is a major challenge as Hadoop is not inte...
