An XML Document Warehouse Model

Abstract

Abstract. EXtensible Markup Language (XML) has rapidly gained importance as a mechanism for the exchange of information amongst heterogeneous sources over the web. In order to deal with the challenging task of managing the large volumes of data appearing, encoded in XML transactional databases, the need to explore the XML Document Warehouse (XDW) approach is initiated. The applications of the Requirement Engineering (RE) process and ObjectOriented conceptual models have proven their usefulness in building successful software models and solutions. In this paper we introduce an integration methodology for the development of XDWs. Initially we provide a formal notation of the structural design for the XDW conceptual model. Secondly we focus on deriving requirements for the XDWs by exploring the Goal-Question Metric (GQM) approach. We adapt and extend this concept to XDWs and introduce a method for developing warehouse requirements considering user viewpoints and organizational objectives. The implementation of our proposed warehouse requirement derivation model is demonstrated using a case study example extracted from a simplified real-world scenario.

Finding an application-appropriate model for XML data warehouses

“…The initial researches that provide XML-based multidimensional modelling [13,43,45,47] can handle more complex data than previous proposals (i.e. complex datacentric XML documents).…”

“…As in [6], the authors use XML views to define dimensions over the XML warehouse data. This work has been complemented in [46] and an associated methodology for the definition of user requirements has been defined in [47].…”

Engineering XML Solutions Using Views

“…To address such an issue, the authors of the work [46,47], proposed an XML-view based design methodology for modeling and designing XML document warehouses (XDW), using our view model for modeling dimensional (XML) data. Later they extended their work to accommodate web content in Web (XML) document warehouse design [48].…”

Semantic modeling of e-solutions using a view formalism with conceptual & amp; logical extensions

“…Document Warehouse Design Enterprise Content Management (ECM) [46] is a data intensive task, especially when handling large volumes of distributed heterogeneous data, such as data warehousing. To address such an issue, the authors of the work [48], proposed an XML-view based design methodology for modeling and designing XML document warehouses (XDW), using our view formalism (conceptual and logical views) for dimensional (XML) data modeling [48,49]. Later they extended their work to accommodate web content in Web (XML) document warehouse design [50].…”
