Vistas analíticas de referencia de esquema de estrella

Vistas analíticas de SSB

Las vistas analíticas permiten ampliar fácilmente un esquema de estrella con un modelo de negocio jerárquico, reglas de cálculo de agregación y medida, metadatos específicos de la aplicación y de presentación que se pueden utilizar para mejorar el contenido de un juego de datos y para simplificar el desarrollo de aplicaciones de inteligencia empresarial. El esquema SSB incluye una vista analítica y cuatro jerarquías que utilizan las tablas del esquema de estrella. Utilice las siguientes consultas para consultar la vista analítica de SSB de ejemplo. Tenga en cuenta que la vista analítica está en el esquema SSB.
