---------------

    Because scripts are so powerful and flexible, their possible uses are
    endless.  Scripts are primarily used to write what is called *business
    logic*.  Business logic is different than presentation logic.
    Presentation logic is usually written in a presentation language, like
    DTML, and its purpose is to display information to a user.  Business
    logic is usually written in a scripting language, and its purpose is to
    manipulate information that comes from content sources (like documents
    or databases) or manipulate other objects.  Often, presentation logic
    is based *on top of* business logic.

       I don't know whether "business logic" is a standard term for the scripting languages and the programs that
       work with the information delivery, but I don't really agree with it. Not all, and nearly not all the
       scripting is business related and its logic isn't always dealing with e-commerse-type of functionality. Thus,
       for example some script doing firewall log parcing and delivering it to the web-interface does more of an
       administrative task then business with its logic.
       Just an opinion.

       A good point. Not that you should use a different term than Business Logic (if that's the standard term), but
       you should note that it's not just for "business" processes. Otherwise, some readers will worry that - since
       they aren't primarily interested in financial code - they're in the wrong place.
