Two-tier client/server Tier 2 Tier 1 Micro/ server Mainframe Local-area network Function: Presentation Function: Application Logic MMIS 656 / Introduction to Internet
Two-tier System • Client-Server model is based on the idea of separating functionality. • Presentation function (i.e., all the programs responsible for painting the screen, mouse, keyboard operations etc.) is placed on the client. • Application Logic function (i.e., all the programs which process data) are placed on a separate server. • Common Logic is available to all clients on the server. MMIS 656 / Introduction to Internet
Three-Tier Model • The next model is based on the following: • Presentation on client • Application Logic on the Server • Data on a separate tier MMIS 656 / Introduction to Internet
Three-tier Client/Server Model Local-area network Application logic Presentation Note: many clients per application server, several application servers per data server Shared data MMIS 656 / Introduction to Internet
