24 Object Relational Mapping module:
25 * Hierarchical structure
26 * Constraints consistency and validation
27 * Object metadata depends on its status
28 * Optimised processing by complex query (multiple actions at once)
29 * Default field values
30 * Permissions optimisation
31 * Persistant object: DB postgresql
33 * Multi-level caching system
34 * Two different inheritance mechanisms
35 * Rich set of field types:
36 - classical (varchar, integer, boolean, ...)
37 - relational (one2many, many2one, many2many)

1644 :raise AccessError: * if user tries to bypass access rules for read on the requested object.
1646 **Expressing a search domain (args)**
1648 Each tuple in the search domain needs to have 3 elements, in the form: **('field_name', 'operator', value)**, where:
1650 * **field_name** must be a valid name of field of the object model, possibly following many-to-one relationships using dot-notation, e.g 'street' or 'partner_id.country' are valid values.
1651 * **operator** must be a string with a valid comparison operator from this list: ``=, !=, >, >=, <, <=, like, ilike, in, not in, child_of, parent_left, parent_right``
1652 The semantics of most of these operators are obvious.
1653 The ``child_of`` operator will look for records who are children or grand-children of a given record,
1654 according to the semantics of this model (i.e following the relationship field named by
1655 ``self._parent_name``, by default ``parent_id``.
1656 * **value** must be a valid value to compare with the values of **field_name**, depending on its type.
1658 Domain criteria can be combined using 3 logical operators than can be added between tuples: '**&**' (logical AND, default), '**|**' (logical OR), '**!**' (logical NOT).
1659 These are **prefix** operators and the arity of the '**&**' and '**|**' operator is 2, while the arity of the '**!**' is just 1.
1660 Be very careful about this when you combine them the first time.

1666 The '&' is omitted as it is the default, and of course we could have used '!=' for the language, but what this domain really represents is::
