In conjunction with database roles, users and the permissions you grant them enable you to manage the permissions
logical model users have to insert, select, update, delete, alter, or reference entities, tables, and views in the logical
database. In addition to being supported by tables and views in the physical data model, depending on the database
platform, users also can be applied to specific physical models to manage system privileges such as those required to
backup databases and logs, or to create databases, defaults, procedures, rules, tables, and views. The system
privileges available are database dependent and display on page 2 of the User Wizard and User Editor.
Database users are supported by the logical data model and are also supported by physical data models for the
following platforms:
• IBM DB2 for LUW 5.x, 6.x, 7.x, 8.x, 9.x
• IBM DB2 for OS/390 5.x and 6.x, and DB2 for z/OS 7.x, 8.x, 9.x
• Microsoft SQL Server 4.x, 6.x, 7.x, 2000, 2005
• Oracle 7.x, 8.x, 9i, 10g, 11g
• Sybase ASE 11.0, 11.5, 11.9, 12.0, 12.5, 15
NOTE: The User Wizard and User Editor share the same options, except for Attachment Bindings options
which are present only in the editor.
1 In the Data Model Window, expand the Main Model of the Logical model, or of a physical model for which
database users are supported, right-click the Users node, and then click New Database User.
2 In the User Wizard, assign the permissions desired, and then click Finish.
The following describe options that require additional explanation.
NOTE: Options and permissions available are platform-dependant.
General page/tab
• User Name: The restrictions for the number of character permitted when defining user and group names is
dependant on the database platform.
• Is Group: Members of a user group automatically inherit group privileges. Privileges granted to a user override
the privileges associated with any groups the user is a member of, and are retained if the user is later removed
from the groups. Explicit privileges granted to a user must be explicitly revoked.
• Password: When selected, specifies that the user is a local user who must specify a password when accessing
the database.
• Externally: When selected, specifies that the user is an external user who must be authorized by an external
service, such as an operating system or third-party service, to access the database.
• Globally: When selected, specifies that the user is a global user who must be authorized to use the database by
the enterprise directory service or at login.
• Add: When clicked, the Select Roles dialog appears where you can select the roles to assign to the user. Hold
CTRL-Shift to select multiple roles. If you have not previously defined a role, the list will be empty.
• Tablespace Quota: On some physical models, you can define tablespace usage parameters (in units of 10KB).
This will limit a user’s ability to grow a tablespace, but should not be used instead of designed range limits.
System Privileges page/tab
Clicking the column name selects the entire column. Control-click to select multiple objects. The permissions
available are dependant on the physical platform selected.
