SPARQL

SPARQL (SPARQL Protocol and RDF Query Language) is a powerful tool used to query and retrieve data from databases that store information in a format called RDF (Resource Description Framework). RDF organizes data as a web of connected information, much like a graph. SPARQL allows users to ask complex questions about this data, enabling them to find specific pieces of information, filter results, and even combine data from different sources seamlessly. It's widely used in fields like semantic web and linked data, helping to connect and make sense of vast amounts of interconnected information.
