Pathfinder: XQuery - The Relational Way [PDF]
, 2005 Relational query processors are probably the best understood (as well as the best engineered) query engines available today. Although carefully tuned to process instances of the relational model (tables of tuples), these processors can also provide a ...

Semantic Protocol and Resource Description Framework Query Language: A Comprehensive Review
Mathematics, 2022 This review presents various perspectives on converting user keywords into a formal query. Without understanding the dataset’s underlying structure, how can a user input a text-based query and then convert this text into semantic protocol and resource ...

Data Model and Query Constructs for Versatile Web Query Languages [PDF]
, 2006 As the Semantic Web is gaining momentum, the need for truly versatile query languages becomes increasingly apparent. A Web query language is called versatile if it can access in the same query program data in different formats (e.g. XML and RDF). Most

Development of Use Cases, Part I [PDF]
, 2004 For determining requirements and constructs appropriate for a Web query language, or in fact any language, use cases are of essence. The W3C has published two sets of use cases for XML and RDF query languages.

Journal of Computer and System Sciences, 1995 AbstractWe investigate the relationship between programming with constraints and database query languages. We show that efficient, declarative database programming can be combined with efficient constraint solving. The key intuition is that the generalization of a ground fact, or tuple, is a conjunction of constraints over a small number of variables ...

The optics of language-integrated query [PDF]
Science of Computer Programming, 2020 Monadic comprehensions reign over the realm of language-integrated query (LINQ), and for good reasons. Indeed, comprehensions are tightly integrated with general purpose programming languages and close enough to common query languages, such as SQL, to guarantee their translation into effective queries.
