Project Entities
The Technical Project Manager module uses a unique representation to store descriptions of what makes a project : the autonumbering tree_shaped entity representation.
A description entity is a treeset of entries, each one able to be indefinitely divided into sub-entites. Thus requirements might be divided into sub-requirements, specifications into sub-specifications, tasks into sub-tasks and deliverable description into sub-deliverables down to a single ressource.
The "Milestone" is the only one which is list-shaped.
Entities are autonumbering i.e. it will renumber automatically entries using a hierarchical numeric numbering starting from 1 within each level. Numbering is uniform :
- The sub-entry just following a level N entry WILL be at level N+1, and will be locally numbered starting from 1.
- Numberings of successive entries within the same sub-branch will be in following order.
Thus the tree :
1, 1.1, 1.2, 1.2.1, 1.2.2, 1.3
is legal, conversely to such illegal tree :
1, 1.1, 1.2, 1.2.1.1, 1.2.1.2
in which the subnode 1.2.1 is missing.
