Normalization of an already normalized relation
Created by: Piiit
Is the following assumption correct?
/* * Create a subquery to handle temporal normalization, if not done * already by the GROUP BY PERIOD transformation above. Normalization * of a already normalized relation has no effect, if the same bounds * and non-temporal attributes are used. * PEMOSER Check if this is always the case if period group by and * distinct period are both set. */
