Ingresar mas tablas en una base de datos

Te recomiendo crees un usuario nuevo de base de datos diferente al de scott
Uno que lleve el nobre de lo que quieras ponerle a tu schema!
Te envio el siguient script que te crea un usuario de base de datos
---
Lo que tienes que hacer es:
Donde esta cat sustituyelo por el nombre que le quieras dar a ese usario de base de datos
Y
Donde dice sami_data debes poner el tablespace que alojara la data de tu base de datos y donde dice temp, debes poner el nombre del tablespace que funcionara como tablespace temporal
Y donde aparece sami_index colocaras el nombre del tablespace que almacenara los indices de tu base de datos
!
Si no te sabes los nombres de estos tablespace
Me dices y te envio un script para que obtengas los nombres de ellos y me los envies y te podre decir cuales debes usar!
Luego de que hagamos esto te dare los script para la creacion de tablas en oracle!
