An Event Oriented Data Management Method for Displaying Genealogy with a New Function for Direct Descent Family Lines

A lot of existing genealogy display software cannot perfectly display complex relations, including historical science and ethnology. Therefore, we have constructed a new software so that it can. Our software uses an event oriented data management method, the "White Base" (Widespread Hands to Interconnect Basic Elements). It is a hidden node for integrating the relations, including a married couple and their children. Using the White Base, the number of references is less than the existing data structure, and complex multiple marriages with segment intersections can be displayed perfectly. This method, however, cannot manage some different line styles of the family trees. To cope with this difficulty, a new function is installed on the previous software. As a result, normal family trees and "Direct Descent Family Lines", can be switched automatically and seamlessly without changing the White Base model. Our improved prototype software that can show the effectiveness of our research is presented.
