Date's Twelve Rules for Distributed Database Systems



Date's Twelve Rules for Distributed Database Systems / Twelve Objectives for Distributed Database System

Note: it is hard to attain all the twelve rules for any distributed database systems. Currently no Distributed Database Management Systems conforms to all the twelve rules.
