XML-OLAP: A Multidimensional Analysis Framework for XML Warehouses [chapter]

Byung-Kwon Park, Hyoil Han, Il-Yeol Song
2005 Lecture Notes in Computer Science  
We base XML-OLAP on XML warehouses where every fact data as well as dimension data are stored as XML documents. We build XML cubes from XML warehouses.  ...  In this paper, we propose a new framework for multidimensional analysis of XML documents, which we call XML-OLAP.  ...  In Section 3.2, we present how to build an XML warehouse from the given XML document set.  ...

X-warehouse

Ji Zhang, Wei Wang, Han Liu, Sheng Zhang
2005 Special interest tracks and posters of the 14th international conference on World Wide Web - WWW '05  
In this paper, we propose an approach to materialize XML data warehouses based on the frequent query patterns discovered from historical queries issued by users.  ...  The schemas of integrated XML documents in the warehouse are built using these frequent query patterns represented as Frequent Query Pattern Trees (FreqQPTs).  ...  INTRODUCTION Building an enterprise wide XML data warehouse system is usually extremely time and cost consuming that is unlikely to be successful.  ...

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.  ...  In this paper, we propose a unified XML warehouse reference model that synthesizes and enhances related work, and fits into a global XML warehousing and analysis approach we have developed.  ...  XML-OLAP is based on an XML warehouse where every fact and dimension is stored as an XML document.  ...

Enhancing XML Data Warehouse Query Performance by Fragmentation [article]

Hadj Mahboubi
2009 arXiv   pre-print
XML data warehouses form an interesting basis for decision-support applications that exploit heterogeneous data from multiple sources.  ...  We particularly focus on the initial horizontal fragmentation of dimensions' XML documents and exploit two alternative algorithms.  ...  XML-OLAP is based on an XML warehouse where every fact and dimension is stored as an XML document.  ...

Building XML Data Warehouse Based on Frequent Patterns in User Queries [chapter]

Ji Zhang, Tok Wang Ling, Robert M. Bruckner, A Min Tjoa
2003 Lecture Notes in Computer Science  
In this paper, we propose an approach to materialize XML data warehouses based on frequent query patterns discovered from historical queries issued by users.  ...  Using hierarchical clustering technique, the integration approach in the data warehouse is flexible with respect to obtaining and maintaining XML documents.  ...  Acquire Data to Feed the Warehouse The last step of building the XML data warehouse is to read data from XML data sources when the schemas of the integrated XML documents are ready.  ...

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  
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.  ...  Therefore, the importance of integrating XML documents in data warehouses is becoming increasingly high.  ...  We say that an XML document supports an XML fact when it is valid against an XML star schema or an XML snow flake schema representing a logical model of a warehouse.  ...
