Comparison of triplestores

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

This is a comparison of triplestores, also known as subject-predicate-object databases. Some of these database management systems have been built as database engines from scratch, while others have been built on top of existing commercial relational database engines (e.g., SQL-based).[1] Like the early development of online analytical processing (OLAP) databases, this intermediate approach allowed large and powerful database engines to be constructed for little programming effort in the initial phases of triplestore development. Long-term though it seems that native triplestores will have the advantage for performance. A difficulty with implementing triplestores over SQL is that although triples may thus be stored, implementing efficient querying of a graph-based RDF model (e.g., mapping from SPARQL) onto SQL queries is difficult.[2]
