Database Connectivity

The Wolfram Language includes powerful capabilities for working with many types of external databases, including relational (SQL), object store (NoSQL) and triple store (RDF/SPARQL). Wolfram Language entity stores are also closely integrated with relational databases, allowing many analysis operations specified in the Wolfram Language to be automatically executed in external relational databases.
