What Are The Main Differences Between Centralize And Distributed Database?
From WIkepedia: A distributed database is a database that is under the control of a central database management system (DBMS) in which storage devices are not all attached to a common CPU. It may be stored in multiple computers located in the same physical location, or may be dispersed over a network of interconnected computers. A Centralized database is a database located and maintained in one location, unlike a Distributed database.
