# global database link

A database link that links each database in a network to all other databases. This enables any user of any database in the network to specify a global object name in a SQL statement or object definition.

An Oracle Names server can store global database links.

For example, a connection to a remote database with the global database link of `sales.us.acme.com` would be:

       CONNECT@sales.us.acme.com

| Note: A global database link that matches the database global database name is automatically registered with the Oracle Names server.
