Based Middleware In The Trick System

This paper is based on the online enrollment system of high school, which is a large-scale distributed information management system based on the Internet and also a new enrollment mode that transmits all kinds of information about enrollment job and controls the whole enrolling workflow through the computer network. The goal of this system is to enhance the informatization degree and the efficiency of enrollment job, reduces its the communication burden. It can change the traditional enrollment mode which taking the paper files as the only medium. All the information and files of examinees, enrolling-plan of school are changed to electronic type, and also, all the information in the enrollment is transmitted by electronic data form between enrollment central office with each school through the network. The system is composed of the spot branch system, the data agency delivers system and the client tier long-range enrollment branch system, which used by the filiations enrollment office and school.High school recruitment system is a typical loose coupling distributional information system, which is also a distributional multimedia coordinating system at the same time. The key problem of the distributional multimedia application is about the QoS management and control of multimedia. In the article, a QoS management model of application layer based on the middleware is designed, this frame permits the users and the application carry on the applicative frame to the QoS management strategy and the compatible adjustment strategy. This article designs the general resources connection and it's concrete realization method in the resource management. The function that the general connection should have, what should be done in its coordination with QoS manager, and its simple implementation in the secondary school recruitment system are also proposed out in the article.All of these are based on the network layer and operating system from application layer angle.The technique of data agency middleware is studied mainly. This is an effective method that reduces the network current capacity, enhances the speed of response, and increases the security of the system. The data agency middleware downloads the few data, which related to the application of customer, to the clients where the data will be processed locally, and uploads the processed results to the server. All of these done can achieve the buffer of various kinds of data, enhance the information...
