" Data base maintenance

" Auditorium control
* Data base transmission
These categories represent three major areas of
operator expertise which are system control, ad-
ministration, and maintenance. Each area is
equally important to the total system operation
and each area requires personnel who have been
trained to perform specific tasks in those
The mos: used administrative function is that
of data base enrollment and data base maintenance.
The next few paragraphs present a short expla-
nation on the purpose of the ECS data base and a
brief example of the procedure used to change an
individual's data base record. This will serve
to illustrate the basic methods employed by man
to communicate with the ECS.
The ECS data base holds a record for every
individual working within the TA-55 complex.
These records must be accurate rt all times since
they contain important authorization and statLe
information. Only personnel holding cleared
Laboratory badges and with a need to enter the
area on a regular basis are enrolled in the ECS
data base. All other personnel are enrolled in
the data base on a daily basis as cleared or un-
cleared visitors and are issued visitor badges.
The data base is checked and purged at regular
intervals to ensure its integrity is always at the
All operators must know the fireL-level pass-
word thst is required to gain access to the ECS.
This level will permit the operator to enter re-
quests for only certain displays and reports. In
order to manipulate the data base, the operator
also must know a second password which is known
only to personnel who are authorized to alter the
contents of the data base.
The operator is able to perform the function
of altering the data base by selecting that option
from the operational menus. Figure 1 show the
screen that is displayed when the "ALTER THE DATA
BASE" option has been selected by the operator
fro4 a previous menu. It can be seen that there
are many options available to the operator in
The operator must enter the data base pass-
word as requested by the prompt in the lower left
quadrant. For security reasons, the password will
not appear on the screen as it is being keyed-in.
If the correct password is not entered, the com-
puter will display a message to that effect in the
lower right quadrant and present the corrective
Once the data base password has been vali-
dated by the computer, the message "ENTER OPTION"
will appear on the screen. A "2" is entered for
the "CHANGE A RECORD" option and the screen shown
in Fig. 2 will bL immediately displayed.
The operator is given the option to iarch
for the individual's data base record using either
name or Z-Number as the eey. In this case, a "I"
was entered and the prompt "ENTER Z-NUMBER" ap-
peared on the screen. When the operator enters
the Z-Number and the record is found, the screen
shown in Fig. 3 will be displayed.
The contents of the individual's data bat'
record are nnw displayed in the upper left quad-
rant. The prompt now reads "ENTER FiELD NUMBER"
permitting the operator to change the contents of
any of the fields in the record. Once all the
