Complete Geometric Query Languages

Marc Gyssens, Jan Van den Bussche, Dirk Van Gucht
1999 Journal of computer and system sciences (Print)  
Concretely, we introduce bothcoordinate-based and point-based query languages that are complete in the sense that they can express precisely all computable queries that are generic with respect to certain  ...  We also show that the respective basic point-based languages are complete relative to the subclass of the corresponding generic queries consisting of those that are expressible in the relational calculus  ...  Acknowledgments The authors wish to thank Jan Paredaens and Bart Kuijpers for interesting discussions related to generic geometric queries.  ...

Marc Gyssens, Jan Van den Bussche, Dirk Van Gucht
1997 Proceedings of the sixteenth ACM SIGACT-SIGMOD-SIGART symposium on Principles of database systems - PODS '97  
We also introduce natural point-based geometric query languages that are complete relative to the basic class of queries expressible in the relational calculus with real polynomial constraints.  ...  We introduce query languages for spatial databases that are complete, in the sense that they can express precisely all computable queries that are generic with respect to certain classes of transformation8  ...  We then use this result to find complete geometrical query languages under various geometrical interpretations.  ...

RESEARCH ON EXTENSION OF SPARQL ONTOLOGY QUERY LANGUAGE CONSIDERING THE COMPUTATION OF INDOOR SPATIAL RELATIONS

C. Li, X. Zhu, W. Guo, Y. Liu, H. Huang
2015 The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences  
Also a method is proposed to analysis the query language.  ...  The ontology concepts are used in IndoorSPARQL query language which extends SPARQL syntax for representing and querying indoor space.  ...  Based on geometric model and symbolic model, the current indoor query services focus on geometric and simple semantic query, such as range query and k nearest neighbor query.  ...

On query languages for linear queries definable with polynomial constraints [chapter]

Luc Vandeurzen, Marc Gyssens, Dirk Gucht
1996 Lecture Notes in Computer Science  
Whether any of the proposed extensions is complete for the linear queries de nable in FO + poly remains open.  ...  For querying linear databases, the language FO + linear has been proposed. We present both negative a n d positive results regarding the expressiveness of FO+linear.  ...  As we s h o wed with a counterexample, our construction can lead to unsafe query languages if that restriction is lifted.  ...

A pictorial query language for querying geographic databases using positional and OLAP operators

Elaheh Pourabbas, Maurizio Rafanelli
2002 SIGMOD record  
Moreover, the possibility to use the mentioned language to query multidimensional databases is discussed. Finally, the characteristic of the mentioned language by a query example is shown.  ...  The authors propose a declarative Pictorial Query Language (called PQL*) that is able to express queries on an Object-Oriented geographic database drawing the features which form the query.  ...  The Pictorial Query Language: PQL* By the pictorial query language (PQL*) complex queries can be expressed by simple and intuitive pictorial operations.  ...

Ontology Modeling and Storage System for Robot Context Understanding [chapter]

Eric Wang, Yong Se Kim, Hak Soo Kim, Jin Hyun Son, Sanghoon Lee, Il Hong Suh
2005 Lecture Notes in Computer Science  
We first design a relational data schema appropriate for Web Ontology Language (OWL) documents, and then develop a transformation mechanism from OWL documents to the relational schema.  ...  Using Jena, we can store XML-based semantic web documents including RDF, RDFS, DAML+OIL and OWL, and query the stored documents with RDQL query language.  ...  Up to date, several semantic query languages are proposed, for example, such as RQL and RDQL for querying RDF and RDFS documents, DQL for DAML+OIL documents, and OWL-QL for OWL documents.  ...

Adding domain-specific and general purpose language features to Java with the Java language extender

Eric Van Wyk, Lijesh Krishnan, Derek Bodin, Eric Johnson
2006 Companion to the 21st ACM SIGPLAN conference on Object-oriented programming systems, languages, and applications - OOPSLA '06  
We demonstrate several language extensions. One embeds the SQL database query language into Java and statically checks for syntax and type errors in SQL queries.  ...  Other extensions for the domain of computational geometry provide transformations that simplify the writing of efficient and robust geometric algorithms.  ...  that they want to use in writing a program with both database query and geometric aspects to it.  ...

Visual Querying in Geographic Information Systems [chapter]

Valéria Gonçalves Soares, Ana Carolina Salgado
2002 Visual and Multimedia Information Management  
This article presents a framework that defines a visual query language for Geographical Information Systems (GIS).  ...  The queries use visual elements and visual spatial operators, which are represented according to a Geographic Visual Query Language, the GeoVisualQL.  ...  When we talk about visual languages we mean that they are completely different from textual languages in terms of their formalization.  ...

The language of the queries expressible by linear inequalities is usually referred to as FO + linear.  ...  Such geometric objects are called semialgebraic sets. Similarly, queries are expressed by polynomial inequalities. The query lan- guage thus obtained is usually referred to as FO+ poly.  ... 

Foundation of the DISIMA Image Query Languages

2004 Multimedia tools and applications  
This approach is necessary in order to envision a declarative query language for images.  ...  Both languages are declarative and allow the combination of semantic and similarity queries.  ...  The DISIMA query language is MOQL (Multimedia Object Query Language), a declarative text-based multimedia query language , which is an extension of the standard OQL language (Cattell et al., 1997) .  ...
