MMIS 656 / Introduction to Internet2 Two-tier client/server Local-area network Mainframe Micro/ server Tier 1 Tier 2 Function: Presentation Function: Application Logic
MMIS 656 / Introduction to Internet3 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 Internet4 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 Internet5 Presentation Application logic Shared data Local-area network Note: many clients per application server, several application servers per data server Three-tier Client/Server Model
