Think of it in another way: a family tree is just an org chart. There are tons of apps out there that present org charts. Grandparents may be the equivalent of executives, parents of managers, children of workers... It's also very similar to thinking of products within subcategories within categories within product lines.
Like Clint says, it's just a matter of getting the relationships straight in the db and figuring out the hierarchy from there. I would do something like linking every person's record with his owner or parent. So if I select the family tree for Ferguson, I'm going to start with someone at the top and I'll be able to get all of the people with him/her (or a couple) as their owner. You could have two "owner" fields to get mom and dad... It should be simple enough to follow that query down to little Lauren who, as the youngest Ferguson, has nobody calling her the owner. I would fall easily in line with my Brother, as we've the same two owners... It's also now very simple to see, specifically who my cousins are by querying for a list of people whose owners have the same owners as my owners (this would be much easier on a whiteboard). Do you get where I'm coming from??? --Ferg -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Clint Tredway Sent: Tuesday, March 01, 2005 8:26 AM To: [email protected] Subject: Re: Family Tree? this is done by setting up the people relationships correctly. I can think of 2 ways off the top of my head on how to do this, but it depends on your SQL knowledge as to which one I would use. The most basic way would be to have a main Person table and a linking table PersonPerson table. The linking table can store the link between people and the type of relationship (uncle,cousin,friend,etc)... The more advanced way would be to have a vertical table where all people are stored and you would loop through the table to get the relationships... Granted this is an high level desc but you should see what I am talking about.
