A triplestore or RDF store is a purpose-built database for the storage and retrieval of triples through semantic queries. A triple is a data entity composed of subject–predicate–object, like "Bob is 35" (i.e., Bob's age measured in years is 35) or "Bob knows Fred".
Much like a relational database, information in a triplestore is stored and retrieved via a query language. SPARQL is the W3C-standardized query language for querying RDF data, and is implemented by most actively maintained RDF triplestores. Unlike a relational database, a triplestore is optimized for the storage and retrieval of triples. In addition to queries, triples can usually be imported and exported using the Resource Description Framework (RDF) and other formats.
