Hi everyone, Apologies if this is a dumb question, I have had a good look through the archives and on the web. My question is basically about how to design a website. I really like the ease with which you can build applications in zope but I often see comments implying that in order to scale well one may want to use a backend relational datbase. I have also seen several comments to the effect that one should keep the state of a user session out of the ZODB. I am slightly confused by this, I can't find any information which would help me decide what data would be better off in a relational database. Example, to learn my way around zope I am deesigning a simple blogging application which allows people to log into the site and see blogs they have subscribed too. I would represent the blog posts as a series of ZPT documents. Two questions, is it better to represent the blog posts as objects in the database or as records in an external relational database? And as regards users, should I use Zope's userfolders for authentication or an external database of usernames and passwords? Again I apologize if this is a ridiculous question and if someone can point me in the direction of some good resources about the overall design of a zope site that would be very helpful.
