Dimensiones en el diseño de un modello de vistas orientadas a objetos

En este trabajo presentamos el modelo de vistas definido para el modelo de datos orientado a objetos Chimera, comparandolo con las propuestas mas relevantes de mecanismos de vistas orientadas a objetos. La comparacion se organiza en tres dimensiones: i) el posicionamiento de una vista en el esquema existente, ii) la naturaleza de la extension de una vista y iii) las actualizaciones sobre vistas. La discusion planteada sirve para analizar la problematica general de la definicion de vistas orientadas a objetos.
