1、EXP:
有三种主要的方式（完全、用户、表）
1、完全：
EXP SYSTEM/MANAGER BUFFER=64000 FILE=/data/full.dmp FULL=Y
如果要执行完全导出，必须具有特殊的权限
2、用户模式：
EXP SONIC/SONIC BUFFER=64000 FILE=/data/sonic.dmp OWNER=SONIC
这样用户SONIC的所有对象被输出到文件中。
3、表模式：
EXP SONIC/SONIC BUFFER=64000 FILE=/data/t_sonic.dmp OWNER=SONIC TABLES=(SONIC)
这样用户SONIC的表SONIC就被导出
2、IMP:
具有三种模式（完全、用户、表）
1、完全：
IMP SYSTEM/MANAGER BUFFER=64000 FILE=/data/full.dmp FULL=Y
2、用户模式：
IMP SONIC/SONIC BUFFER=64000 FILE=/data/sonic.dmp FROMUSER=SONIC TOUSER=SONIC
这样用户SONIC的所有对象被导入到文件中。必须指定FROMUSER、TOUSER参数，这样才能导入数据。
3、表模式：
EXP SONIC/SONIC BUFFER=64000 FILE=/data/t_sonic.dmp OWNER=SONIC TABLES=(SONIC)
这样用户SONIC的表SONIC就被导入。
