When should database synonyms be used?

Question

I\'ve got the syntax down but I\'m wondering if somebody can provide an illustrative use case where database synonyms are very useful.

Answer 1

Say, when you need to make a poorly written application (that does not issue ALTER SESSION SET CURRENT_SCHEMA) to work against another schema.

The synonyms are mainly used as a workaround for cases like that. With a properly written application, you will hardly ever have to use them.
