Essential Performance Drivers in Native XML DBMSs [chapter]

Theo Härder, Christian Mathis, Sebastian Bächle, Karsten Schmidt, Andreas M. Weiner
2010 Lecture Notes in Computer Science  
XML query processing is critically affected by the smooth interplay of concepts and methods on all architectural layers: node labeling and mapping options for storage structures; availability of suitable  ...  index mechanisms; provision of a spectrum of path processing operators; query language compilation and optimization.  ...  Even more compression gain could be expected for document-centric XML content. Indexing Options Set-oriented access to the nodes of an XML document is supported by a variety of index types.  ...

Managing e-commerce catalogs in a DBMS with native XML support

L. Lim, M. Wang
2005 IEEE International Conference on e-Business Engineering (ICEBE'05)  
Our solution does not require a separate query optimization layer, because query optimization is handled within the hybrid DBMS engine itself.  ...  By leveraging on System RX's hybrid nature, we present a novel solution for storing, managing, and querying e-catalog data.  ...  , (2) new index types for XML data including structural indexes, value indexes, and fulltext indexes, (3) a hybrid query compiler that can process XQuery and SQL, and (4) an enhanced query runtime that  ...

A Scalable Approach to Processing Large XML Data Volumes

Tim Weitzel, Thomas Tesch, Peter Fankhauser
2003 Americas Conference on Information Systems  
The emerging penetration of IT architectures with XML leads to increasing XML data volumes. Available tools often fail in realizing scalable XML processing for large XML data volumes.  ...  Based on concrete application scenarios it is illustrated how Infonyte-DB can be deployed for XML based web services, technical documentation, and mobile information management.  ...  User-Defined Indices Structural indices are not sufficient for content-based queries to large XML documents and document collections.  ...

A framework for retrieval and annotation in digital humanities using XQuery full text and update in BaseX

Cerstin Mahlow, Christian Grün, Alexander Holupirek, Marc H. Scholl
2012 Proceedings of the 2012 ACM symposium on Document engineering - DocEng '12  
We have developed a system for systematic, iterative exploration and annotation of historical text corpora, which relies on an XML database (BaseX) and in particular on the Full Text and Update facilities  ...  A key difference between traditional humanities research and the emerging field of digital humanities is that the latter aims to complement qualitative methods with quantitative data.  ...  Context is defined as a certain number of preceding or following text nodes. Index structures are mandatory if large databases are to be queried.  ...

Locking-aware structural join operators for XML query processing

Christian Mathis, Theo Härder, Michael Haustein
2006 Proceedings of the 2006 ACM SIGMOD international conference on Management of data - SIGMOD '06  
As observed in many publications so far, the matching of twig pattern queries is a core operation in XML database management systems (XDBMSs) for which the structural join and the holistic twig join algorithms  ...  To circumvent this problem, we propose a set of new locking-aware operators for twig pattern query evaluation that rely on stable path labeling IDs (SPLIDs) as well as document and element set indexes.  ...  Together with appropriate index structures, a labeling scheme for tree nodes is most influential for efficient access to XML documents.  ...
