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)

5921 Various implementations were tested on the corpus of all browse() calls
5922 performed during a full crawler run (after having installed all website_*
5923 modules) and this one was the most efficient overall.
5925 A possible bit of correctness was sacrificed by not doing any test on
5926 Iterable and just assuming that any non-atomic type was an iterable of
5931 # much of the corpus is falsy objects (empty list, tuple or set, None)
5935 # `type in set` is significantly faster (because more restrictive) than
5936 # isinstance(arg, set) or issubclass(type, set); and for new-style classes
5937 # obj.__class__ is equivalent to but faster than type(obj). Not relevant
5938 # (and looks much worse) in most cases, but over millions of calls it
5939 # does have a very minor effect.
