Model driven development of secure XML data warehouses
Belén Vela, Carlos Blanco, Eduardo Fernández‐Medina, Esperanza Marcos · 2010
Data Warehouses (DWs) are currently considered to be the cornerstone of Business Intelligence (BI) systems. Security is a key issue in DWs since the business information that they manage is crucial and highly sensitive, and should be carefully protected. However, the increasing amount of data available on the Web signifies that more and more DW systems are considering the Web as the primary data source through which to populate their DWs. XML is therefore widely accepted as being the principal means through which to provide easier data and metadata interchange among heterogeneous data sources from the Web and the DW systems.
