The Consume Application System Of Campus Card Based On B/S Architecture

The paper analyzes the feasibility of use Ethernet in measure-control system, and introduces the "Versatile Campus Card" developing status in our country. After compares C/S architecture and characteristic with B/S, bases on university's developmental character and trend in our country, the thesis puts forward an B/S architecture synthesis application system model, --"The synthesis Application System Of Versatile Campus Card Consume System", which based on Ethernet and TCP/IP protocol in distributed compute environment.There are four main characteristics of this system: First, adopt Ethernet as measure-control network, can utilize existing hardware resources effectively. Second, adopt C/S to combine with B/S mode, the ground floor uses Active x technology, lower control adopt C/S mode run as a tray, the upper stratum manage use B/S, lower and upper strata software communicate with each other by Message Middleware. Third, adopt both way dissymmetry technology, that is update remote database use stored procedure, and gather data from remote database use transaction replicate technology. Fourthly, task and trigger technology has been adopt to optimize database. This system can achieve use one card in school effectively, even if several schoolyard distributing in different geography place. Active x, message middleware, and SQL Server 2000 task and transaction replicate technology which are used in system have been introduced detailed.As idiographic realization of the card synthesis application system SDK, the thesis analyses and modeling every module in Versatile campus consuming, and introduces several main model's data and program flow chart detailed. Finally, the paper introduces system test and running state.
