Subject: Re: Updating a database of object with CLOS From: Erik Naggum <erik@naggum.no> Date: 22 Nov 2002 03:10:40 +0000 Newsgroups: comp.lang.lisp Message-ID: <3246923440767292@naggum.no> * delaregue@netscape.net (Delaregue) | Is there a way to save only updated information? How about only saving changes by appending to the file? This will in effect be a transaction log and you can even achieve real transactions by saving `begin´ and `commit´ forms so you can save changes made in each update method and then finalize them. Every once in a while, do a full save of the database. All of this may be accomplished with a meta-class. -- Erik Naggum, Oslo, Norway Act from reason, and failure makes you rethink and study harder.
