Another important measurement that is to be taken is to record the column count
of key tables that store instance related data before and after applying the pur-
ging. As these tables in the Dehydration Store have no foreign keys, there is
always a case where purging leaves dangling or orphaned instances in some of
the tables. Executing the following script provided here, measures the column
count in the various Dehydration Store tables. If executed before and after ini-
tializing purging, you can determine whether the purging scripts have effectively
deleted instance data completely.
