• A single database (on server) can be shared across several distinct client (application) systems. The elements that make up the tables include phone numbers, names, dates, dollar amounts and other specific data. As, described earlier, the client is now responsible for application’s user interface, thus it requires less computational resources now clients are called as ‘thin client’ and it requires less maintenance. A relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as invented by E. F. Codd, of IBM's San Jose Research Laboratory. The database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. Database Management System â The world of data is constantly changing and evolving every second. These machines are spread (or distributed) geographically and connected together by a variety of communication networks. Example of a centralized database system.
