This statement generates the additional name NEGATIVE for the table 'person'. This name can be written anywhere instead of the old name. Since it is a user-specific name, it has the advantage that it can be specified without user identification.
CREATE SYNONYM negative FOR person
Several synonyms can be defined for one table. They can neither be used nor be seen by other users.
Synonyms are particularly useful for abbreviating long or complicated table names. Especially, when accessing tables of other users, the user name specification before the table name can be omitted.
