FUNCTIONAL REQUIREMENTS

Other system features include:

DISTRIBUTED DATABASE

Distributed database implies that a single application should be able to operate transparently on data that is spread across a variety of different databases and connected by a communication network as shown in above figure.

CLIENT/SERVER SYSTEM

The term client/server refers primarily to an architecture or logical division of responsibilities, the client is the application (also known as the front-end), and the server is the DBMS (also known as the back-end).

A client/server system is a distributed system in which,

• Some sites are client sites and others are server sites.

• All the data resides at the server sites.

• All applications execute at the client sites.
