+* Principe
+
+** Scenario
+
+A scenario is defined by a name, a description and a parent
+scenario. If a scenario as no parent, parent value is =None=. So, in
+Pamhyr2 the list of scenario must by a tree with a root defined by a
+default scenarios with no parent.
+
+#+begin_src sql
+  CREATE TABLE scenario(
+    id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,
+    name TEXT NOT NULL,           -- Name of the scenario
+    description TEXT NOT NULL,    -- Rich text description
+    parent_id INTEGER REFERENCES scenario(id) -- Recursive references
+                                              -- for parent scenario
+  )
+#+end_src
+
+** Data
+
+Each data is associated with one and only one scenario. This senario
+is defined by the =id=. So, each data structure who can saved in DB
+must add the following lines in table définition:
+
+#+begin_src sql
+  scenario_id INTEGER NOT NULL,
+  FOREIGN KEY(scenario_id) REFERENCES scenario(id)
+#+end_src
+
+To avoid, at least, memory usage exploitation, by default, a scenario
+must saved only the modified data from its parent. This contrains
+require to wrap any data modification to update the data scenario id
+to current scenario id in source code. In addition, we need to modify
+the data loading méthode to take in considération this recursive
+dependencies.
+
+#+CAPTION: Recursive loading method
+#+begin_src python :python python3 :results output :noweb yes
+  def rec_load(cls, db, current_scenario):
+    # Default case, end of recursion
+    if current_scenario is None:
+      return []                   # Default value
+
+    table = db.execute(f"<MY SELECT> WHERE scenario_id = {current_scenario}")
+
+    # If no data for this scenario, recursion
+    if len(table) == 0:
+      parent_id = db.get_parent_id(current_scenario)
+      return cls.rec_load(db, parent_id)
+
+    # Otherelse, parse data and return...
+#+end_src
+
+With this method, modify a data in parent scenario, modify this data
+in child scenario too. Unless is value has been previously modified in
+the child scenario. Deny tree node modification, except for leaf.
+
+This method work, but it dont allow to delete data un child scenarios,
+because if we dont found data for this scenario we search for parent
+scenario. So, we need a condition to stop recursion in case of data
+deletion in child scenario. To stop the recurtion, we can use a dummy
+data flag. By default, this flags is =false=, but if this flags is
+=true= the data is ignored at loading.
+
+So, we can use this flags for each data structure who can saved in DB:
+
+#+begin_src sql
+  is_dummy BOOLEAN,               -- True if this data as been deleted
+#+end_src
+
+Modify the loading method:
+
+#+CAPTION: Recursive loading method with possible dummy data
+#+begin_src python :python python3 :results output :noweb yes
+  def rec_load_2(cls, db, current_scenario):
+    # Default case, end of recursion
+    if current_scenario is None:
+      return []                   # Default value
+
+    table = db.execute(f"<MY SELECT> WHERE scenario_id = {current_scenario}")
+
+    # If no data for this scenario, recursion
+    if len(table) == 0:
+      parent_id = db.get_parent_id(current_scenario)
+      return cls.rec_load(db, parent_id)
+
+    for data in table:
+      if is_dummy(data):
+        continue
+
+      # Otherelse, parse data ...
+
+    # return ...
+#+end_src
