Authorize Teradata Database Users

You can use the Authorization editor to make an association between a database user and an OS server user ID in a Teradata physical model. Using the authorization feature, you can let an external routine run in a secured mode using the context, permissions, and access control given to the specified OS user.

In Teradata, objects are owned by databases or users. A database and a user are equivalent with the exception that only a user can login to the database. A database or a user can act as a schema.

Note: Passwords will not be stored, but you can use a UDP to generate a password for forward engineering.
