2.6 USER ITEM PROTECTION MAINTENANCE

This is a special SENTRY feature which allows you to define SENTRY security objects. These objects

may be accessed through subroutine calls to solve unique security problems which may not be met through

permissions and VOC item security facilities. For example, you may have a personnel inquiry screen in

which you would like to limit the display of the salary field to only a certain group. Through defining a

user item which specifies the rights for users and/or groups, you may then add a call to the

SENTRY.USER.ITEM.CONTROL subroutine to check the rights of the user before displaying the salary

field. By using this technique, individual fields may be protected in data entry/inquiry programs as well as

in the database reporting language. You may also call our violations logging subroutine to log program or

report use.

“Database Maintenance Menu” invokes this program.

Use of this feature of SENTRY requires some programming effort. Because of the flexibility of the

SENTRY routines, this effort is generally very nominal. For an experienced Basic programmer, SENTRY

offers a very sophisticated level of security for very little effort. Please refer to the appendices for

documentation of the user callable SENTRY subroutines, the arguments, and examples on how to

implement their use.
