The main purpose of TAG is to help maintain security while making your job easier, faster and more reliable. To do this, TAG breaks down the display and update of all information by screens.
Screens contain devices that speed up data entry and retrieval while at the same time reduces the chances of making mistakes. To make TAG more reliable, we designed the screens so that they are fully integrated: for example, if an officer changes an offender's housing location on one screen, that same information will appear on all other TAG screens that show the offender's housing location from then on. You only have to update information once.
Screens also contain security devices that protect them from being retrieved if you don't have access privileges. You can only access information in the TAG database through TAG screens, and the screens you can retrieve depends on your access privileges. Taking the above example where an offender's housing location was changed, you can retrieve this information only if you have access privileges to screens that show the offender's housing location. You can change the offender's housing location only if you have access privileges to screens that allow the offender's housing location to be changed.
