Final answer:
Understanding the role of URIs and Namespaces is useful when using SPARQL because it enhances query performance, facilitates integration with relational databases, and provides a standardized way to identify and reference RDF resources.
Step-by-step explanation:
When using SPARQL, understanding the role of URIs and Namespaces is useful for several reasons:
- Enhances query performance: URIs allow for faster and more efficient retrieval of data, as each resource is uniquely identified.
- Facilitates integration with relational databases: URIs and Namespaces provide a standardized way to identify and reference RDF resources, allowing for seamless integration with relational databases.
- Provides a standardized way to identify and reference RDF resources: By using URIs and Namespaces, SPARQL queries can identify and reference specific resources in RDF datasets, enabling interoperability and reuse of data.
