Need for Client Server Computing-Client/Server (C/S) architecture includes running the application on multiple machines in which every machine with its component software tackles only a part of the job. Client machine is mainly a PC or a workstation that gives presentation services & the appropriate computing, connectivity & interfaces while the server machine gives database services, connectivity & computing services to multiple users. Both client machines & server machines are connected to the similar network. While the number of users grows, client machines can be added to the network whereas as the load on the database server enhances more servers can be connected by the network. Therefore, client-server combination is a scalable combination. Server machines are more powerful machines database services to multiple client requests.

The client-server systems are connected by the network. This network require not only be the Local Area Network (LAN). It can also be the Wide Area Network across multiple cities. The client & server machines communicate by standard application program interfaces (known as API), and remote procedure calls (RPC). The language by which RDBMS based C/S environment communicate is the structured query language (SQL).
