Foundations of a New Proposal for Querying Relational Databases and XML Documents [chapter]

Ana Fermoso García, María José Gil Larrea, Luis Joyanes Aguilar, Jesús Luis Díaz Labrador
2003 Lecture Notes in Computer Science  
One solution would be an integrated query model that would at the same time allow the query of a relational database and of XML data.  ...  After having made a detailed study, in this paper we make comparing different systems that link both, databases and XML. Besides, we propose a new system to overcome the limitations found in them.  ...  A New Database Query System Based on XML The main aim is to create a system that allows querying relational database and XML documents using the same query system in an efficient way.  ...

Query Formulation and Evaluation for XML Databases [chapter]

Kiyoshi Akama, Chutiporn Anutariya, Vilas Wuwongse, Ekawit Nantajeewarawat
2002 IFIP Advances in Information and Communication Technology  
Evaluation of a query on a specified XML database is carried out by employment of Equivalent 'I'ransformation paradigm.  ...  The proposed approach to XML query formulation and evaluation developed by means of XML Declamtive Description (XDD) theory formalizes a query as an XDD description comprising one or more XML clauses the  ...  Thus, the proposed approach to query formulation and evaluation can be utilized as a foundation for the processing of XML queries, expressed in other languages.  ...

A query language for XML

Alin Deutsch, Mary Fernandez, Daniela Florescu, Alon Levy, Dan Suciu
1999 Computer Networks  
XML-QL is a declarative, "relational complete" query language and is simple enough that it can be optimized. XML-QL can extract data from existing XML documents and construct new XML documents.  ...  We present a query language for XML, called XML-QL, which we argue is suitable for performing the above tasks.  ...  Specifically, we take a database view, as opposed to document view, of XML. We consider an XML document to be a database and a DTD to be a database schema.  ...

XBiT: An XML-Based Bitemporal Data Model [chapter]

Fusheng Wang, Carlo Zaniolo
2004 Lecture Notes in Computer Science  
The approach can be generalized naturally to support the temporal management of arbitrary XML documents and queries on their version history.  ...  The increasing popularity of XML and XQuery offers a unique opportunity to change this situation, inasmuch as these support temporal information much better than relational tables and SQL.  ...  For instance, XPERANTO can build a default view on the whole relational database, and new XML views and queries upon XML views can then be defined using XQuery.  ...
