Modelling stars using XML

Jaroslav Pokorny
2001 Proceedings of the 4th ACM international workshop on Data warehousing and OLAP - DOLAP '01  
A star schema, a well-known technique used in data warehousing, can be applied. Then dimension information is supposed to be contained in XML data.  ...  Due to the structural complexity of XML data the approach requires subtler formal model than it is done with conventional dimension and fact tables described by classical star schemes.  ...  DIMENSION MODELLING In the first step, we introduce star schemes where each dimension is modelled by a single table (so called simple stars). Then we enrich the dimension using a simple hierarchy.  ...

Conversion of XML Schema to Data Warehouse Schema using Automatic Approach

Thidar Win
2014 International Journal of Computer Applications  
We define more than one Data Warehouse schemas from the given XML schema using the Schema Graph has been proposed in the conversion process.  ...  XML is used by many organizations for e-commerce and internet based applications such as online shopping, digital library, and electronic devices and so on.  ...  As compared to previous approaches based on DTD, the higher expressiveness of XML schema allows more effective modeling. Moreover, this paper uses XML schema to handle semi-structure data.  ...

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  
The resulted XML Schema represents the logical model of a data warehouse.  ...  Whereas, XML documents validated against the analysis objectives define the physical model of the data warehouse, called the XML cube.  ...  XML-star schema [7] uses Document Type Definitions (DTDs) to explicit dimension hierarchies.  ...

A Quantitative Summary of XML Structures [chapter]

Zi Lin, Bingsheng He, Byron Choi
2006 Lecture Notes in Computer Science  
As xml has been widely used, e.g. for online data exchange, the need for (corresponding) statistical summaries in xml has been evident.  ...  By using our approach, we illustrate that some popular real-world and synthetic xml benchmark datasets are indeed highly skewed and hardly hierarchical and contain few recursions.  ...  Otherwise, the impedance mismatch between the tree model and the relational model can become problematic where native xml/xml-based approaches should be adopted.  ...

XML Data Warehouse: Modelling And Querying [chapter]

Jaroslav Pokorny
2002 Databases and Information Systems II  
We adapt the traditional star schema with explicit dimension hierarchies for XML environment. We propose the notion of XML-referential integrity for handling XML-dimension hierarchies.  ...  Some their data sources are repositories of XML data or they are viewed as XML data independently on their inner implementation. In this paper, we study the foundations of XML data warehouses.  ...  Tree-and graphoriented models are used also for DTDs (e.g. [LC00] , [PV00] ).  ...

Multidimensional Analysis of XML Documents: Modeling and Implementation

Kais Khrouf, , Jouf University, Saudi Arabia
2019 International Journal of Emerging Trends in Engineering Research  
In this paper, we propose a new multidimensional model of semi-structured data (XML documents), based on complementary dimensions (Content, Metadata, Structure, Semantics...) and we integrate also the  ...  In order to access, visualize, aggregate and analyze their data, the organizations generally use the techniques of data warehouses and OLAP (On-Line Analytical Processing).  ...  The authors of [11] use the star schema and propose three types of dimensions for modeling documents. The Ordinary Dimension constitutes a list of terms extracted from the document.  ...

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.  ...  However, its usage induces new theoretical and practical challenges at the modeling, storage and analysis levels, and a new trend toward XML warehousing has been emerging for a couple of years.  ...  XML data warehouses In his XML-star schema, Pokorný (2002) models a star schema in XML by defining dimension hierarchies as sets of logically connected collections of XML data, and facts as XML data elements  ...
