A “Branch” is the fundamental unit used to locate and define data.
Each Branch has three relationship pointers that logically tie all Branches together: Parent, Sibling, and Child.
There is only one Parent for a given Branch. “/A” is the Parent of “/A,B”.
A Branch can have one Sibling. The Sibling can in turn point to another Sibling. “/A,C” is the Sibling of “/A,B”.
A Branch can have one Child. The Child can in turn have related Siblings and Children. “/A,B” is the Child of “/A”.
Siblings and Children are always in an ordered sequence. “/A,C” will come after “/A,B” and “/A,B” will be the Child of “/A”.
Data associated with a Branch is in one or more Sections. A Branch can be stored or communicated as a File. A File is associated with one Branch. A Branch can have one File or none.
