family-tree

I am trying to generate pedigree (in other words family tree :) ) table from database... My schema: CREATE TABLE `horses` ( `horse_id` int(10) NOT NULL AUTO_INCREMENT, `horse_name` varchar(32) NOT NULL, `horse_sire` int(10) DEFAULT NULL, `horse_dam` int(10) DEFAULT NULL, PRIMARY KEY (`horse_id`), KEY `FKsire` (`horse_sire`), KEY `FKdam` (`horse_dam`), CONSTRAINT `FKdam` FOREIGN KEY (`horse_dam`) REFERENCES `horses` (`horse_id`), CONSTRAINT `FKsire` FOREIGN KEY (`horse_sire`) REFERENCES `horses` (`horse_id`) ) p.s. 'horse_dam' and 'horse_sire' represents parents... I have spent days on this

Suppose I have the below code in my familyTree.pl file: male(tom). male(bob). female(lisa). female(emily). parent(tom, bob). parent(lisa, bob). morethanfriends(emily, bob). father(X,Y) :- male(X), parent(X,Y). mother(X,Y) :- female(X), parent(X,Y). girlfriend(X,Y) :- female(X), (morethanfriends(X,Y); morethanfriends(Y,X)). boyfriend(X,Y) :- male(X), (morethanfriends(X,Y); morethanfriends(Y,X)). Now, I want to get the answer to the questions like: What is the relationship between Tom and Bob ? What is the relationship between Lisa and Emily ? How can I ask the above questions to prolog? The

could someone point me to a working use of a graph database for genealogy? I would like to learn neo4j and I use python so I was looking to make a genealogy graph db for myself to learn graph db's. I searched for examples to emulate and learn from (any graph db, any language) but was surprised how little I found. Note I mean graph db which has a different structure than a relational db. See http://en.m.wikipedia.org/wiki/Graph_database . I'm looking for an example schema for genealogy. If you want to learn to do graphdb, you don't need to use any software. Pencil, paper and brain will do. The

I am creating Family Tree feature for my web app with HTML5 requirements. I already searched and found some JS samples, but I haven't find any that fit with my requirements. I already tried JIT, Rafael, GoJS, etc. I found this to be the closest one is from GoJS: GoJS fam-tree option #1 But this not enough. I need to connect one member with another member with drag and drop function. Is there some JS that may fit with the

I want to generate this: With this data structure (ids are random, btw not sequential): var tree = [ { "id": 1, "name": "Me", "dob": "1988", "children": [4], "partners" : [2,3], root:true, level: 0, "parents": [5,6] }, { "id": 2, "name": "Mistress 1", "dob": "1987", "children": [4], "partners" : [1], level: 0, "parents": [] }, { "id": 3, "name": "Wife 1", "dob": "1988", "children": [5], "partners" : [1], level: 0, "parents": [] }, { "id": 4, "name": "son 1", "dob": "", "children": [], "partners" : [], level: -1, "parents": [1,2] }, { "id": 5, "name": "daughter 1", "dob": "", "children": [7],

I have a family tree from Cyril's amazing answer but I'm trying to figure out how to adjust it to support multiple partners. In this case, I added a "Mistress" node and am trying to denote that "Mistress" and "John" had a child named "Hidden Son". The current data structure works like this: In that, the root object stores everything. It has a children array which contains the up most "generation" with no parents. It also contains an object that contains the children of these sibling objects/nodes. In the example above, this is root.children[2] . I'm thinking I would have to refactor the data
