24 Object relational mapping to database (postgresql) module
25 * Hierarchical structure
26 * Constraints consistency, validations
27 * Object meta Data depends on its status
28 * Optimised processing by complex query (multiple actions at once)
29 * Default fields value
30 * Permissions optimisation
31 * Persistant object: DB postgresql
33 * Multi-level caching system
34 * 2 different inheritancies
36 - classicals (varchar, integer, boolean, ...)
37 - relations (one2many, many2one, many2many)

1971 **Expressing a search domain (args)**
1973 Each tuple in the search domain needs to have 3 elements, in the form: **('field_name', 'operator', value)**, where:
1975 * **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.
1976 * **operator** must be a string with a valid comparison operator from this list: ``=, !=, >, >=, <, <=, like, ilike, in, not in, child_of, parent_left, parent_right``
1977 The semantics of most of these operators are obvious.
1978 The ``child_of`` operator will look for records who are children or grand-children of a given record,
1979 according to the semantics of this model (i.e following the relationship field named by
1980 ``self._parent_name``, by default ``parent_id``.
1981 * **value** must be a valid value to compare with the values of **field_name**, depending on its type.
1983 Domain criteria can be combined using 3 logical operators than can be added between tuples: '**&**' (logical AND, default), '**|**' (logical OR), '**!**' (logical NOT).
1984 These are **prefix** operators and the arity of the '**&**' and '**|**' operator is 2, while the arity of the '**!**' is just 1.
1985 Be very careful about this when you combine them the first time.

1989 [('name','=','ABC'),'!',('language.code','=','en_US'),'|',('country_id.code','=','be'),('country_id.code','=','de'))
1991 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::

5069 Example with both max_hours and max_count active:
5070 Suppose max_hours = 0.2 (e.g. 12 minutes), max_count = 20, there are 55 rows in the
5071 table, 10 created/changed in the last 5 minutes, an additional 12 created/changed between
5072 5 and 10 minutes ago, the rest created/changed more then 12 minutes ago.
5073 - age based vacuum will leave the 22 rows created/changed in the last 12 minutes
5074 - count based vacuum will wipe out another 12 rows. Not just 2, otherwise each addition
5075 would immediately cause the maximum to be reached again.
5076 - the 10 rows that have been created/changed the last 5 minutes will NOT be deleted
