DirectToWeb describes a technology that STILL, some nine years after its introduction, points to a logical future for how data-driven web applications ought to be developed. DirectToWeb is an expert system applied to web applications. "The general architecture of an expert system involves two principal components: a problem dependent set of data declarations called the knowledge base or rule base, and a problem independent (although highly data structure dependent) program which is called the inference engine." http://en.wikipedia.org/wiki/Expert_systems The WebObjects developer that wishes to use DirectToWeb to create his application manipulates the rules in the rule base to result in the desired behaviour. The DirectToWeb frameworks contain the inference engine that is used to determine what rules will be fired.
