| A Feature can be stored in many tables of database. Restoring that feature
may be did by join, the resulting table can be explored using this iterator
class. This iterator return Features with simple or complex attributes.
In the FeatureTypeMapping must be defined the grouping attributes, this value
will be used to distinguish different features in the data sotore.
The next can be a posible data store.
