Figure 5. Relational representation of property tables RDF stores
Figure 6. Relational representation of binary tables RDF stores
Figures 4, 5 and 6 illustrate examples of the three alternative relational representation of the sample RDF
graph (Figure 1) and their associated SQL queries for evaluating the sample SPARQL query (Figure 2).
