The advantage of the FAT client (c/S mode) application is that both the client and the server can handle the task, the client's requirements are higher, but can reduce the pressure of the server, which is used in the enterprise internal management system. Disadvantage is the system client software installation, maintenance difficulties, the database system can not meet the demand for a large number of terminals at the same time, a large number of client/server data communication is not suitable for remote connection, can only be suitable for LAN applications. A part of the module of C/s system changes, it is necessary to link to other modules of the changes, the system upgrades maintenance costs.

The advantage of thin client (b/s mode) applications is its flexibility. Any time, place, system, as long as the use of browser access to the Internet, you can use the B/s system terminals, currently in the network of remote office systems, E-commerce sites and other systems in a large number of uses. The disadvantage is that this structure of the client browser, must always have network connectivity, and can only complete browsing, query, data entry and other simple functions, most of the work by the server, the burden of the server is very heavy. This mode of development, maintenance and so on almost all the work is concentrated on the server side, the system maintenance and upgrade the cost is low.

Smart Client (SC/S mode) applications combine the advantages of a FAT client (c/s mode) with a thin client (b/s) application, which can be deployed without contact, automatic updating, dynamic loading, and easy offline use. The management system with all or part of the following characteristics is suitable for using this mode: Make full use of local computer resources, play the function of client, use network resources to solve the problem of Information Island, support remote landing, support stand-alone work in network without connection, provide intelligent installation and update, and support client device flexibility This model is of high cost but convenient application and low maintenance cost.
