Client-server computing model and comparison of commercially available database servers

Clients and servers are separate logical entities that work together over a network to accomplish a task. Client-server computing is a technique applied when one portion of an application focuses on servicing the end-user and local processing while another provides a server function to respond to the client requests.;The objective of this thesis is to build a client-server computing model and to review and compare three commercially available database servers offered by three different vendors, based on this model. The practical advantages of database servers and several different features of a database server are discussed in this study. Each factor and feature, however, should be weighed in light of the savings in development costs and improved application quality it would provide on actual projects.;Future research directions for client-server computing are proposed and three important future trends that would impact client-server architecture are discussed.
