X-WACoDa: An XML-based approach for Warehousing and Analyzing Complex Data [article]

Hadj Mahboubi, Sabine Loudcher, Jérôme Darmont
2017 arXiv   pre-print
Unfortunately, no standard XML data warehouse architecture emerges.  ...  Data warehousing and OLAP applications must nowadays handle complex data that are not only numerical or symbolic. The XML language is well-suited to logically and physically represent complex data.  ...  The authors show how data warehouse multidimensional design may be carried out starting directly from XML sources.  ...

Finding an application-appropriate model for XML data warehouses

Franck Ravat, Olivier Teste, Ronan Tournier, Gilles Zurfluh
2010 Information Systems  
These proposals range from using XML data sources for regular warehouses to those using full XML warehousing solutions.  ...  Finding an appropriate model for an XML data warehouse tends to become complicated as more and more solutions appear.  ...  Finally, others map XML source data to a multidimensional model, i.e. maintain source XML files and produce a mapping to designate factual and dimensional data within the XML files.  ...

A Software Architecture for XML-Based Metadata Interchange in Data Warehouse Systems [chapter]

Gunnar Auth, Eitel von Maur
2002 Lecture Notes in Computer Science  
Interchanging metadata between software components of a data warehouse environment is the foundation for leveraging the various benefits of an integrated metadata management for data warehousing.  ...  We therefore propose a software architecture for metadata interchange that incorporates a shared metamodel to agree on metadata syntax and semantics, XML as a standard interchange language, and XML Metadata  ...  Future research will concentrate on how to integrate metadata that cannot be extracted from DWH components, but resides in various other sources.  ...

X-Warehousing: An XML-Based Approach for Warehousing Complex Data [chapter]

Omar Boussaid, Riadh Ben Messaoud, Rémy Choquet, Stéphane Anthoard
2006 Lecture Notes in Computer Science  
XML is suitable for structuring complex data coming from different sources and supported by heterogeneous formats. It allows a flexible formalism capable to represent and store all types of data.  ...  We propose an XML-based methodology, called X-Warehousing, which designs warehouses at a logical level, and feeds them with XML documents at a physical level.  ...  Our approach does not only use the XML formalism to design data warehouses (or data cubes), but also feeds them with data. We use XML documents to support information relative to the designed facts.  ...
