Those links doesn't give you a clear idea.

Aliases and synonyms are alternate names given the data base object. Using these will ease programming because since we are not hardcoding the table names with full qualifiers in the query, it becomes simple to use the code in different regions like testing, development production etc...
Synonyms can be created only on existing objects and they get deleted when the object is deleted.
alias can b created even if the object is not available and remains even if the object is deleted.
Hope this helps... |
