Un Conjunto de Transformaciones QVT para el Modelado de Almacenes de Datos Seguros

Resumen. La seguridad es un aspecto crucial para el desarrollo de los Almacenes de Datos (DWs) ya que estos contienen datos sensibles. Este hecho requiere la necesidad de especificar requisitos de seguridad y de auditoria en el modelado multidimensional, que no pueden ser directamente transformados al modelo relacional del DW. El marco estandar para el desarrollo del software Model Driven Architecture (MDA) permite definir transformaciones entre modelos mediante la propuesta Query/View/Transformations (QVT). Esta propuesta permite definir transformaciones de una manera formal, elegante e inequivoca. En este articulo utilizamos QVT para transformar al esquema logico relacional del DW toda la informacion de seguridad representada en el modelo conceptual multidimensional.
