What are the benefits of centralized databases?
In a centralized database, all data is stored and maintained in one place. The central location is a computer or database. All the data is stored in a single location for an example mainframe computer. Show This database mostly maintains and modifies using internet connection like LAN and WAN. The centralized database mostly used in colleges, banks, hospitals and in small companies. In a centralized database system one computer act as a server for storing whole data. In a centralized database system, client/server architecture is used it is the very simplest form of a database system in which one client sent a request to the server. The server will receive a request and will be a response. Many small organizations use a centralized database system. Characteristics of a Centralized Database SystemPresence of a global clock:As the whole system consists of a central computer (a server/ a master) and many client computers (a computer/ a slave), all client nodes connect up with the global clock(the clock of the central node). One single central unit:The central server will communicate with all clients. All clients send a request to the server and the server will be the response. Dependent failure of components:When the server goes down all systems will be destroyed. The client is not able to access the database Advantages of Centralized Database SystemSome advantages of a Centralized Database Management System are:
