Abstract

Las rutinas de manipulacion de la base de datos en una base de datos que se llevan a cabo por medio de un servidor de la base de datos al determinar si se va a aislar o no la rutina de manipulacion de la base de datos de un rango específico de memoria, y, en respuesta, cambiar de forma selectiva el permiso para el acceso de memoria al rango de memoria específico (por ejemplo desde lectura y escritura hasta solamente lectura) para la rutina de manipulacion de la base de datos bajo consideracion. Luego, la rutina de manipulacion de la base de datos se ejecuta utilizando el permiso para el acceso de memoria cambiada selectivamente. La rutina de manipulacion de la base de datos que se va a aislar se puede ejecutar con un acceso a la memoria solamente de lectura, por lo que se protege un rango específico de memoria (por ejemplo la correspondencia a las estructuras de datos centrales) de modificaciones inadecuadas.
