“When developing a Web application, it’s standard
practice to create a database structure on which server-side code
is placed for the logic and UI layers. To connect to the database,
the server-side code needs to do some basic creating, updating,
deleting, and — most importantly — reading of records.
As databases behind Web applications are typically relational
databases, these CRUD operations are done using the well-known
language, SQL. However, as Web development is increasingly
occurring through object-oriented programming (OOP), the model is
changing.“The Resource Description Framework (RDF) is a perfect way to
describe objects while maintaining the meaning of that data. Simple
Protocol and RDF Query Language (SPARQL — pronounced
“sparkle”) is the language typically used to query against that
data, as it syntactically matches the structure of RDF itself. Both
RDF and SPARQL are technologies within what has been dubbed the
semantic Web stack.”
