Conceptual Design of an XML FACT Repository for Dispersed XML Document Warehouses and XML Marts

Since the introduction of extensible Markup Language (XML), XML repositories have gained a foothold in many global (and government) organizations, where, e-commerce and e-business models have maturated in handling daily transactional data among heterogeneous information systems in multi-data formats. Due to this, the amount of data available for enterprise decision-making process is increasing exponentially and are being stored and/or communicated in XML. This presents an interesting challenge to investigate models, frameworks and techniques for organizing and analyzing such voluminous, yet distributed XML documents for business intelligence in the form of XML warehouse repositories and XML marts. In this paper, we address such an issue, where we propose a view-driven approach for modeling and designing of a Global XML FACT (GxFACT) repository under the MDA initiatives. Here we propose the GxFACT using logically grouped, geographically dispersed, XML document warehouses and Document Marts in a global enterprise setting. To deal with organizations' evolving decision-making needs, we also provide three design strategies for building and managing of such GxFACT in the context of modeling of further hierarchical dimensions and/or global document warehouses
