Note:
When results are being deleted as part of a backup
and delete or a delete-only operation, the deletion
can be cancelled. Simply click the Cancel button to
stop the operation. Once Cancel is clicked, depend-
ing on the amount of data being deleted and the size
of the database, there may be significant lag time of
a few minutes before a dialog box appears indicat-
ing that the deletion has been paused, asking you to
select one of three options.
The reason for the lag time is that the program needs to complete whatever
portion of the deletion operation it was performing when the Cancel button
was clicked before it can display the dialog box. Once the dialog box is dis-
played, simply click the desired radio button, then click OK.
Restore test results: This function allows test results that have been deleted from the CDS but backed up

Database File
Backup Database File: This function allows the user to manually perform the same operation that occurs
when the automatic database backup occurs. It creates a complete backup of the database file to the speci-
fied drive/directory.
Compact Database File: When the backup and delete or delete only functions are executed, the deleted
data is removed from the database but the disk space the data occupied in the database file is not. The com-
paction function creates a new copy of the database with the excess space removed, creating a smaller, bet-
ter organized and, therefore, more responsive database. If CDS functions such as opening or refreshing a
data viewer grow noticeably less responsive over time, compaction of the database may help. It is recom-
mended that compaction function be executed at least once a year.
Statistics
A Statistics tab allows users to view a summary page that lists:
■ The total results in the database
■ The date and time of the oldest result in the database
■ The date and time of the newest result in the database
■ A breakdown of the total results in the database by Result
