Common Oracle Data Dictionary

The following table collects almost all views or aliases in the Oracle Data Dictionary. Use the 'describe' statement to query the fields of each view or Alias. Description: In the Oracle Data dictionary, the object names are mostly "USER. "," ALL. "," DBA. "prefix" USER. "The view records the information of the objects owned by the account that normally performs the query," ALL. "view records include" USER "records and information of objects authorized to PUBLIC or users," DBA. "The view contains all database objects regardless of their owner. Example:

Select * from dba_data_files to query table space information (the current user must have the DBA role ). Select owner, object_name, and object_type from all_objects query all tables, processes, functions, and other information of a user.
