7. A database query system comprising: a processor; and a data storage device having stored thereon computer executable program code, which, when executed by the processor, causes the processor to perform a method of: receiving a Simple Protocol And Resource Description Framework Query Language (SPARQL) query; generating a native query from the SPARQL query using a mapping file comprising metadata that describes a multidimensional database; mapping a first Resource Description Framework (RDF) class specified in the SPARQL query with a first column in the multidimensional database; mapping a first property corresponding to the first RDF class specified in the SPARQL query with first values corresponding to the first column in the multidimensional database; executing the native query on the multidimensional database; receiving a native result comprising data stored in the multidimensional database resulting from execution of the native query against the multidimensional database; and generating a SPARQL result from the native result using the mapping file, the SPARQL result representing a response to the SPARQL query.
