Visitors table periodically and deletes the expired data records

depending on the data entered in the database field
DepartDate.
10.3.5 Cleanup Utility (CLU)
The cleanup utility is started daily as a batch process to delete
the access control data that the system no longer needs. Since
this tool has a UCI interface, the user can let it run interactively
on a server if, for example, this process is not started
automatically for some reason. The interactive mode enables
the user to carry out a complete cleansing for all data (as with
the batch processes) or selective data cleansing. The following
sections summarize which data is cleansed.
Deleting personal data
When deleting per dialog, personal data is only flagged for
deletion. All data about the person in the relevant tables such
as Lockouts, AuthPerPerson, Fingerprint, Users, etc. is not
actually deleted until a time span of 6 months has passed
(system parameter PersDelTime).
Cleansing of the data flagged for deletion
For some database tables, the deletion of a data record does
not cause an immediate physical removal. In these tables, the
data record is only flagged for deletion. These include, for
example, Authorizations and Devices tables.
There are a number of reasons for this delayed deletion. The
most important reason is that if the DMS should fail, the
buffered messages can still be entered in the logbook correctly
by the MAC.
The cleanup utility deletes all data records that were flagged for
deletion. A system parameter (RecordDelTime) controls the
number of days after which a data record marked for deletion is
also removed physically.
