Database Link

What is a database link?

A database link is a pointer that defines a one-way communication path from one Oracle Database to another database. A database link allows local users to access data on a remote database.

The following link types are supported:
Private database link- belongs to a specific schema of a database. Only the owner of a private database link can use it.
Public database link- all users in the database can use it.
Global database link- defined in an OID or Oracle Names Server. Anyone on the network can use it.
