After studying Jeffrey Shell's ZLDAP package, and the current ZODB system, in the light of recent conversations with Jim Fulton, a few lightbulbs went on with respect to the usefulness of multi-database Zopelications. For example, wouldn't it be keen if regular Zope objects could 'store' object attributes that were actually LDAP entries? Or SQL database records? That would be pretty awesome.
I believe that Jim Fulton has let his mind wander over this already. The general implementation wasn't hard, he said, the problems arise in the details. How, for example, do you remove unreferenced objects from any such database? How do you find out if an otherwise unreferenced object in one database, is not referenced by another one. Also, IIRC, there is an issue with caching and connections, and the question of when to close a connection to a referenced database. But as I was experiencing some jet-lag at the time, and didn't bring a memo recording when I spoke with Jim, I don't remember the full details. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------
