module documentation

Provides an abstraction for obtaining database schema information. Usage Notes: Here are some general conventions when accessing the low level inspector methods such as get_table_names, get_columns, etc. 1. Inspector methods return lists of dicts in most cases for the following reasons: * They're both standard types that can be serialized. * Using a dict instead of a tuple allows easy expansion of attributes. * Using a list for the outer structure maintains order and is easy to work with (e.g. list comprehension [d['name'] for d in cols]). 2. Records that contain a name, such as the column name in a column record use the key 'name'. So for most return values, each record will have a 'name' attribute..

Class	`Inspector`	Performs database schema inspection.
Class	`ObjectKind`	Enumerator that indicates which kind of object to return when calling the ``get_multi`` methods.
Class	`ObjectScope`	Enumerator that indicates which scope to use when calling the ``get_multi`` methods.
Class	`ReflectionDefaults`	provides blank default values for reflection methods.
