Types and Constraints: From Relational to XML Data [chapter]

Nicole L. Bidoit-Tollu
2011 Lecture Notes in Computer Science  
We focus on the one hand on recent work developed for optimizing query and update evaluation for main-memory engines and on the other hand on techniques for checking XML query-update independence.  ...  The goal of this article is to show that, in the context of XML data processing, information conveyed by schema or XML types is a powerful component to deploy optimization methods.  ...  This work has been partially supported by the Codex ANR-08-DEFIS-004 project.  ...

HUX

Ling Wang, Elke A. Rundensteiner, Murali Mani, Ming Jiang
2006 Proceedings of the 15th ACM international conference on Information and knowledge management - CIKM '06  
CONTRIBUTIONS We propose the first pure data-driven strategy for XML view updating, which guarantees that all updates are fully classified.  ...  We then design an interleaved strategy that combines both schema and data knowledge into one update algorithm to perform a complete classification for XML view updates.  ...  While several research projects [1, 4] began to explore this XML view updating problem, they typically provide no guarantee for avoiding view side effects.  ...

XQuery optimization based on program slicing

Jesus M. Almendros-Jimenez, Josep Silva, Salvador Tamarit
2011 Proceedings of the 20th ACM international conference on Information and knowledge management - CIKM '11  
XQuery has become the standard query language for XML. The efforts put on this language have produced mature and efficient implementations of XQuery processors.  ...  the paths in the source XML documents that are really required to resolve the query.  ...  Rather than projecting XML documents, they project XQuery sub-expressions with respect to other sub-expressions querying them.  ...

that are not relevant for update operations.  ...  An experimental study on an XML database shows that our XML schemas provide high query performance on the relevant elements for the workload and, at the same time, low cost of data redundancy on elements  ...  We can verify in Figure 3 that Redundant and Optimized are similar schemas, except for the hierarchy established by the element Research Project.  ...

Deferred Incremental Refresh of XML Materialized Views [chapter]

Hyunchul Kang, JaeGuk Lim
2002 Lecture Notes in Computer Science  
In the Web era where information proliferates, the view concept is also useful for XML documents in a Web-based information system.  ...  Views are often materialized for query performance, and in that case, their consistency needs to be maintained against the updates of the underlying data.  ...  Recently, a dynamic large-scale warehouse for XML documents of Web, out of Xyleme project [8] at INRIA, France, which provides sophisticated database-like services like querying, update control, and  ...

HUX: Handling Updates in XML

Ling Wang, Elke A. Rundensteiner, Murali Mani, Ming Jiang
2006 Very Large Data Bases Conference  
We demonstrate HUX (Handling Updates in XML) which provides a reliable and efficient solution for the XML view update problem.  ...  Given an update over an XML view, our U-Filter subsytem first determines whether the update is translatable or not by examining potential conflicts in both schema and data.  ...  We would like to thank Song Wang, Maged ElSayed and Xin Zhang for their contributions to this project in terms of ideas and systems.  ...

Projective Distribution of XQuery with Updates

Ying Zhang, Nan Tang, Peter Boncz
2010 IEEE Transactions on Knowledge and Data Engineering  
Finally, we discuss how these techniques can be used for updating queries, both under the standard W3C XQUF specification, as well as under an extended semantics that allows to update remote documents.  ...  The pass-by-fragment semantics is subsequently refined to a pass-byprojection semantics by means of a novel runtime XML projection technique, which safely eliminates most semantic differences between the  ...  Runtime XML Projection The extensions we made to XML projection, namely support for reverse/horizontal XPATH axes and fn:root(), fn:id(), fn:idref(), and fn:lang(), could not be trivially integrated in  ...

Michael Benedikt, Angela Bonifati, Sergio Flesca, Avinash Vyas
2005 International Workshop on XQuery Implementation, Experience and Perspectives  
We present a static analysis for determining when this optimization can be exploited.  ...  We focus on an optimization of the "standard semantics", in which updates are performed as soon as they are generated.  ...  Acknowledgements: We thank Jérôme Siméon for many helpful discussions on update semantics, and Andrea Pugliese for his support in implementation of the static analysis routines.  ...
