Abstract
A method and system for navigating hierarchical database views that supports the efficient entry, review, and updating of data using a navigation display that is clear and efficient--yet compact in terms of the screen area used. At any point in the navigation process, the navigation display consists of buttons corresponding to the nodes that lie along the path to the last node visited (the set of previously made choices) and the children of this node (the set of current choices). Unselected and unselectable choices are culled and do not clutter the display. The user navigates up and down the hierarchy and enters data by selecting these buttons. An important feature of the invention is support for multiple instances of database subhierarchies within this navigation process and display. In addition, multiple nodes can be composed to form a single database entry, thereby reducing the size and complexity of the hierarchical database views. Finally, database views that are directed acyclic graphs are also supported--including both serial and parallel traversal techniques.
