query language

A language that allows a user to select records from a database. It may be in the form of typed commands such as the widely used SQL language, a predefined query menu or a query by example (QBE). Query languages are usually included in DBMSs, and stand-alone packages are available for interrogating non-DBMS files. See SQL, query by example and query program.

When it comes to RDF, this software prides itself with such features such as SPARQL Protocol and Query Language support, RDF Data Management and SPARQL integration within SQL.
Taking advantage of SQI independence in terms of query languages and result formats, this article proposes to use SQI not only for querying metadata as it is primarily intended in the context of the CEN/ISSS workshop on learning technology, but also for resolving the locations of learning objects.
This article shows how the adapter developed by the iClass project (iClass Consortium, 2004) takes advantages of SQI independence in terms of query language and resulting formats to resolve learning object locations (i.
The new query language, XQuery, is still evolving, but it will provide a functional language comprised of several kinds of expressions that can be nested or composed with full generality.
In the future, universal translators will automatically translate a query in one particular language into any number of other languages and also translate the results into the original query language.
Note how this plan essentially mirrors the development of query languages and query optimization in relational databases.
Several rule query languages have been proposed so far.
In this paper, we take the first step toward that goal, by formalizing semantics and query languages for databases under mandatory security.
Their interest is in security policy description, rather than in the database concerns of query languages addressed in this paper.
The combination of the SPARQL query language and protocol creates a Web service in its purest sense; running on top of HTTP or SOAP, it provides a standard Web service for anything which asks a question.
