Synonyms
The DBA or any user is allowed to create synonyms for tables, views, and indexes. These alternate names, or aliases, can be used to define shorthand names in place of long, fully qualified names.
After a synonym is created, it can be referenced the same way as the object for which it was created. For example, if you create a synonym for a table or view, issue SELECT statements using the synonym name, just as you use the table or view name.
