Public Synonyms for Data Dictionary Views (263)

Oracle creates public synonyms for many data dictionary views so users can access
them conveniently. The security administrator can also create additional public
synonyms for schema objects that are used systemwide. Users should avoid naming
their own schema objects with the same names as those used for public synonyms.
