A hierarchical navigational system implements a hierarchical organizational system and provides users with a top-down view of a site. Ad hoc systems serve a hypertext organizational structure and typically appear as embedded links in a Web page. A database navigational system implements a database organizational structure. A user types in a word or phrase to find related pages. Most sites should have some form of hierarchical navigational system. Ad hoc systems involve links that are added typically because a hierarchical system can’t accommodate a particular association. Database navigational systems typically appear as an ancillary system but rarely as the primary navigation system for a site.
