Network Access Requirements
To access an external database, you must be able to connect to the network, have access to the external database, and have access to the server on which the external database is located. Database permissions are established using the security features of the external database. If you do not have the proper access permissions, consult your local database administrator.
Note
Some database systems require that a database-specific network package be installed. Consult your database and database driver documentation for details.
