Extrait de A Framework and Comparative Study of Distributed Hetereogeneous Database Management Systems

L'objectif principal de l'approche du syst�me de gestion de bases de donn�es h�t�rog�nes distribu�es est de soutenir l'int�gration de bases de donn�es au-del� des fronti�res organisationnelles, applicatives et g�ographiques. Ceci est r�alis� par des efforts visant � fournir un sch�ma global unifi� et des fonctionnalit�s de requ�te communes aux utilisateurs, sans modifier les syst�mes de gestion de base de donn�es existants ou leurs programmes d'application.

Les m�thodologies de conception pour de tels syst�mes diff�rent les unes des autres de plusieurs fa�ons. La complexit� suppl�mentaire de la traduction entre plusieurs syst�mes et mod�les de donn�es rend les syst�mes de gestion de bases de donn�es h�t�rog�nes distribu�es plus difficiles que les syst�mes de base de donn�es conventionnels.

Cet article identifie les aspects critiques des syst�mes de gestion de bases de donn�es h�t�rog�nes distribu�es. Il vise � fournir une base pour l'�tude de ces syst�mes, l'analyse comparative entre ces syst�mes et les directions pour d'autres extensions.

Description de la librairie

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
