If you have a field named e.g. Last_Updated, then there's nothing
stopping you from writing a program that exports/transfers the data
and then do a

DELETE FROM Graeme_Table WHERE Last_Updated < Current_Date - 183

Though according to webopedia.com, purge is stronger than delete and
should be unrecoverable, so you may want to skip the export/transfer
bit... ;o)
