A query language for NC

open access: yesProceedings of the thirteenth ACM SIGACT-SIGMOD-SIGART symposium on Principles of database systems - PODS '94, 1994
We show that a form of divide and conquer recursion on sets, together with the relational algebra, expresses exactly the queries over ordered relational databases which areNC-computable. At a finer level, we relateknested uses of recursion exactly toACk,k?1. We also give corresponding results for complex objects.

Typed query languages for databases containing queries [PDF]

open access: yesInformation Systems, 1998
Abstract This paper introduces and studies the relational meta algebra , a statically typed extension of the relational algebra to allow for meta programming in databases. In this meta algebra one can manipulate database relations involving not only stored data values (as in classical relational databases) but also stored relational algebra ...

The optics of language-integrated query [PDF]

open access: yesScience 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.

Constraint Query Languages

open access: yesJournal 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 ...

Data Model and Query Constructs for Versatile Web Query Languages [PDF]

open access: yes, 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

A Visual Language for Web Querying and Reasoning [PDF]

open access: yes, 2003
As XML is increasingly being used to represent information on the Web, query and reasoning languages for such data are needed. This article argues that in contrast to the navigational approach taken in particular by XPath and XQuery, a positional ...

Query Language for Complex Similarity Queries [PDF]

open access: yes, 2012
For complex data types such as multimedia, traditional data management methods are not suitable. Instead of attribute matching approaches, access methods based on object similarity are becoming popular. Recently, this resulted in an intensive research of indexing and searching methods for the similarity-based retrieval. Nowadays, many efficient methods
