3. Genealogy System Registration and Login: l Users create personal accounts l A user may have access to several trees at once l Any user may initiate a new tree project, becoming the tree’s “administrator”

4. Genealogy System Creating a Tree: l The system creates a unique ID for every new tree a user creates l 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)

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

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

7. Genealogy System Data Representation: l Five tables are used –Users –Trees –Members –Users -> Trees –Trees -> Members l Relationships between members defined by recursive reference to member IDs
