To create the user name, see Identifier.
CUBRID has two types of users by default: DBA and PUBLIC. At initial installation of the product, no password is set.
- All users have authorization granted to the PUBLIC user. All users of the database are automatically the members of PUBLIC. Granting authorization to the PUBLIC means granting it all users.
- The DBA user has the authorization of the database administrator. The DBA automatically becomes the member of all users and groups. That is, the DBA is granted the access for all tables. Therefore, there is no need to grant authorization explicitly to the DBA and DBA members. Each database user has a unique name. The database administrator can create multiple users simultaneously using the cubrid createdb utility (see How to Use the Database Management Utilities for details). A database user cannot have a member who already has the same authorization. If authorization is granted to a user, all members of the user is automatically granted the same authorization.
