Database links are named schema objects that describe a path from one database to another. Database links are implicitly used when a reference is made to a global object name in a distributed database. To use a database link, either it is public or you own it.

Note: Oracle syntax does not let you alter an existing database link. To change its definition, drop and re-create it.
