Snippet Name: Database Link

Description: Database Links are used to communicate between different databases.

A database link defines a network connection, and, optionally, a username, to use in contacting a remote database. The purpose of using a link is to isolate SQL statements from the underlying, physical network topology. If the location of a remote database changes, only the link need be updated.
