Providing such information supports the goal of many organizations to empower lower-level employees with decision making capabilities. On the other hand, in certain domains developers may deem such access irrelevant or even distracting to the user's task, possibly slowing down time-critical operations. The user typically selects an item on the computer screen to follow its link or chooses from a list of available links. If a link's purpose or destination is not intuitive, its author or the system builder should label it in some way. Hypertext access includes navigational, annotation and view-oriented features.
Navigation transports the user among information items.
View-oriented features enable navigation through local and global overviews, and along recommended paths and guided tours of interrelated items. An analyst, for example, could prepare an annotated guided tour to explain a completed analysis or other process. Two important consequences for systems development follow from the hypertext concept. First, we can define hypertext both as the science of relationships and as a technology for information access and relationship management. Second, a hypertext philosophy or vantage point emerges for thinking about applications.
