Oh my, how can you work with such column and table names? You and any colleagues you may have will probably appreciate
havinga few views over those tables that translate that gibberish to human readable stuff. You could go further and
makethose views updatable (by means of a few rules), but then you run the risk that colleagues start to hug you...
