In this paper, we propose a new data management method for handling relations on genealogy display software easily. It is named "Widespread Hands to InTErconnect BASic Elements (WHIteBasE)". The WHIteBasE is a hidden node for integrating the relations due to an event including a married couple and their children. That is, individual's data does not refer to others directly, and only refers to WHIteBasEs. As a result, the number of references is less than the existing data structure. Therefore, the volume of database is smaller, the complex multiple marriages can be set easily, and the positions of the segment intersections can also be searched easily. Then, display traditional handwriting genealogy can be achieved on computers. Our new prototype software and the effectiveness of our method are shown. ©2010 IEEE.
