A New Multidimensional Model for the Olap of Documents Based on Facets

چکیده
The OLAP (On-Line Analytical Processing) systems provide a multidimensional analysis of voluminous databases by generating a synthetic vision of data. Several studies have focused on the application of these OLAP techniques on structured and semi-structured data, and more specifically XML documents. In this context, we propose a new multidimensional model for the OLAP of XML documents. The proposed model is based on a combination of different standard facets extracted from documents in order to provide more opportunities of analyses for decision makers compared to the classical multidimensional models (star model, snowflake model and constellation model).The proposed model in this paper, said "CobWeb model" is a multidimensional model based on the star model, it is composed by a set of dimensions related to each other, each of which represents one facet.

A Conceptual Model for Multidimensional Analysis of Documents
Data warehousing and OLAP are mainly used for the analysis of transactional data. Nowadays, with the evolution of Internet, and the development of semi-structured data exchange format (such as XML), it is possible to consider entire fragments of data such as documents as analysis sources. As a consequence, an adapted multidimensional analysis framework needs to be provided. In this paper, we in...
متن کاملXML-OLAP: A Multidimensional Analysis Framework for XML Warehouses
Recently, a large number of XML documents are available on the Internet. This trend motivated many researchers to analyze them multi-dimensionally in the same way as relational data. In this paper, we propose a new framework for multidimensional analysis of XML documents, which we call XML-OLAP. We base XML-OLAP on XML warehouses where every fact data as well as dimension data are stored as XML...
