Client Server Applications

Client/Server architecture is one of the central ideas of network computing. Most of today's business applications use this model, in which applications or data are requested from one computer (the client) and provided by another computer (the server). It is usually distinguished from the older, centralized, mainframe computer model by the use of small and dispersed computers. Today, however, even mainframe computers use the Client/Server architecture. The two types of Client/Server architecture are:

Two-tier architecture

The user interface is normally located in the user's desktop and the database processes are handled by a powerful server. The business rules could be handled either by the client or the server, depending on the application. While simple, this architecture offers less scalability and restricts flexibility.

Three-tier or multi-tier architecture

This is an evolutionary step which adds a middle-tier to increase flexibility. The middle-tier could include application servers, transaction processing monitors, and message queue servers. It can provide a variety of services, including message queuing and database staging. This architecture improves performance, flexibility, and scalability, and usually involves complex application development.
