Web-based Real-Time Decision Support System Active XML-based Metadata

The nature of operational data that is frequently updated, and the interest to reflect business environment alterations in the business analysis process to make operational decisions, need more than the typical data warehousing methodology for data integration. In this paper, therefore, we propose a new methodology to dynamically extract real-time data from various internal and external data sources passively, i.e. after receiving the decision making query. We propose a methodology to store and exchange intensional data (in AXML format) to activate and automate the integration of real-time data and updates. AXML database will be proposed as a structural metadata to integrate data from external data sources and manipulate external models for accurate decision making. Our approach should be seen as a complementary, not a replacement, for the data warehousing approach.
