Re: Nested Sets And Pedigrees

>> Make two trees:

• a mother-tree where X is a child of Y if Y is the mother of X, and
• a father-tree where X is a child of Y if Y is the father of X. <<

I am not sure that would work. Consider a family of several generations with both sons and daughter. Fred is the father of (Sally, Tom); Fran is the mother of (Sally, Tom). When Sally gets married and has a grand-daughter, which tree is her child put into?

This is not really a tree, but a graph structure. Maybe a table of (father, mother, child) rows would work better. Received on Fri Apr 05 2002 - 12:00:37 CST
