This presentation gives an overview of the SPARQL query language and how it is different than SQL, which is used for relational databases. Mentions several software tools for SPARQL support: Apache Jena; Redland; Twinkle. Predates the adoption of SPARQL 1.1, but still useful as a basic introduction to simple queries.
