DATA NAVIGATOR INTERFACE

摘要

In the figure, a hypertext browser displays hypertext pages and indicates draggable elements (56, 58) and drop targets (52) on the page being viewed. The browser detects when a user selects a draggable element and drops the draggable element within a drop target. The browser and/or the server to which it is connected examine a class relations matrix having entries for intersections of draggable element references and drop target references in which a matrix entry at an intersection of the draggable element and drop target is identified and used for performing an action which is a function of the matrix entry.
