From: http://www.sum-it.nl/cursus/dbdesign/english/intro030.php3 A quote: ' In addition *the database designer chooses* an action for delete:
* It's /only possible/ to delete a row in the one-table when there a no more related many-rows. * When deleting a row the RDBMS <http://www.sum-it.nl/cursus/dbdesign/english/intro030.php3#rdbms> /automatically/ deletes the related data in the many table. This is called a /cascaded delete/. * When deleting the last 'many' the RDBMS /automatically/ deletes the related 'one' row.'
I'm pretty sure that Postgres does not support the last one automatically. I shall have to do that one by either a chron script or a post trigger.
Does anyone have experience with a database that will do the last one, and what database would that be?
