SYSTEM AND METHOD FOR DISPLAYING AND MANIPULATING HIERARCHICALLY LINKED DATA IN A GENEALOGY DATABASE USING A GRAPHICAL INTERFACE

摘要

A system and method for displaying, searching, manipulating and modifying of hierarchically linked genealogy data in a relational database on a computer system. A graphic representation of the data in the database is displayed on a computer display device. The system uses zooming, a common function used in computer systems, to show more or less information in the database in readable form. Using the computer pointer devices, the data in the database can be manipulated, added, deleted, or moved. The system allows for changing of the root node individual thereby giving a different view of the database, to zoom in or zoom out and save that view of the database for future reference. The system displays all relationships of the data in the hierarchical structure by use of various sizes and type of lines and positions in the structure and shows for example data further away from the root node individual as a progressively smaller graphical image.
