Hi, I've never worked with a persistent object system like Durus before. I think it is quite fascinating(mind blowing, actually. Kudos to you guys ), but I still have my head too wrapped around the relational model. I am trying to build a simple application just to learn the basics of Durus, but everything seems so deceptively simple. I keep wondering if there is something I'm missing. I keep on hitting walls on things like manual indexing(how and when to do it), autoincrement ids(should I use them? Should I use oids at the application level?), how to deal with large objects, what is the best way to do more complex searches and so on. Maybe these are all non-issues and I'm still just too relationaly biased, but I haven't been able to find something resembling a "Durus Best Practices" document or a good code base to study. I would really appreciate if any of you could point me ever so slightly in the right direction. thanks, Daniel Lemos Itaboraí Veja quais são os assuntos do momento no Yahoo! +Buscados http://br.maisbuscados.yahoo.com
