Genealogy System
  • Web-based application for family trees and
    genealogical information
  • Allows groups to work on common projects instead
    of funneling work through a single person
  • Features an intuitive GUI for data entry and tree
    navigation

Genealogy System
  • Registration and Login
  • Users create personal accounts
  • A user may have access to several trees at once
  • Any user may initiate a new tree project,
    becoming the trees administrator

Genealogy System
  • Creating a Tree
  • The system creates a unique ID for every new tree
    a user creates
  • The creator/administrator of a new tree may
    determine the access rights of any other user
    invited to participate
  • Modification allowed (read/write access)
  • Viewing only (read-only access)

Genealogy System
  • Growing a Tree
  • Family trees grow by defining relationships
    that new members have to existing members within
    each tree
  • Parents
  • Children
  • Spouses/Partners
  • Unique IDs are assigned to each new member
  • Relationships are defined automatically

Genealogy System
  • Displaying a Tree
  • Every family member of a tree can become the
    focus of tree display
  • Ancestors
  • Descendants
  • Family trees can be multi-dimensional
  • The system encourages a unified effort to tree
    development instead of multiple trees

Genealogy System
  • Data Representation
  • Five tables are used
  • Users
  • Trees
  • Members
  • Users - Trees
  • Trees - Members
  • Relationships between members defined by
    recursive reference to member IDs
