Un mètode per a la comprovació de restriccions d'integritat en bases de dades deductives bitemporals
Carme Martín Escofet
Abstract:This Ph.D. thesis mainly deals with temporal and deductive databases areas and the aim is to obtain a method for integrity constraint checking in bitemporal deductive databases, analyzing the temporal integrity constraint behavior. The existence of a transaction time dimension is especially useful to reduce the number of transition rules. In the valid time dimension, the temporal dependence of database predicate terms has been explored. Moreover, this Ph.D. thesis provides some research advances bringing toget… Show more
