以下表格中收集了Oracle数据字典中几乎所有的视图或别名，至于每个视图或别名的字段请用‘Describe’语句来查询。命名说明：Oracle数据字典中，对象名称多数以"USER."，"ALL."，"DBA."为前缀"USER."视图中记录通常记录执行查询的帐户所拥有的对象的信息，"ALL."视图中记录包括"USER"记录和授权至PUBLIC或用户的对象的信息，"DBA."视图包含所有数据库对象，而不管其所有者。使用举例：

select * from dba_data_files  
查询表空间的信息(当前用户必须拥有DBA角色)。  
select owner , object_name ,object_type from all_objects  
查询某一用户下的所有表、过程、函数等信息。
