Sinopsis

Les bases de dades són el mecanisme que sutilitza per a emmagatzemar dades de manera permanent. Aquest llibre se centra en lestudi de les bases de dades relacionals, que són les més emprades actualment. Concretament, sen descobreixen els fonaments teòrics i alguns llenguatges que sutilitzen per a treballar-hi: làlgebra relacional i el llenguatge estàndard SQL92. Saber estructurar adequadament la informació que conté una base de dades resulta fonamental. Aquesta tasca sanomena disseny de base de dades i en aquest llibre lhem presentada a partir del model entitat-interrelació, atès que proporciona una notació gràfica que resulta molt familiar a lusuari. Aquesta obra tampoc no oblida que un bon disseny de base de dades ha de complir els requisits de qualitat, recollits en la teoria de la normalització.
