Research On A XML+ASP_based Course-selecting System And Its Access Confliction Solutions

Under the teaching mode of credit hour system, course selection is the base and reference of all teaching activities, even one of the cores of carrying out credit hour system. For that reason, keeping course selection on the rail and making scientific management must be one of the most important content of this teaching mode.Design and development of course selection system can not only realize teaching resources'unified allocation and coordination, but also help to reduce educational administrators'pressure so that can promote changing management mode and improve managers'management thought and level, then help to build a efficient,normative and concerted education management system. At present, although some schools have already provided course selection platform on line, mostly service for the school's special management mode or especial environmental requirement, many human intervention factors in it that lead to over limited the range of the course that can be chosen, which easily causes course selection crowd and so on. Therefore, the positivity,initiative and freedom of students are limited.Through class selection management system of credit hour, the teachers and managerial personnel may, according to the students'choices, flexible decision courses and interesting, actually done. The institute can be also to his condition for choosing classes, both in the allocation and using of teaching resources and time. That saves a lot of manpower, material and financial resources. So research and development of course selection system has great practical significance.Asp technology is mainly used for interactive, dynamic, high-performance Web application. ASP can hang HTML, ActiveX groupware and scripting languages together, it has powerful functions and distinct advantage in the side of management and maintenance, now it is quite a popular web development technique building in the windows platform. The article joins ASP and data-base and XLM technology together, to develop a system that can exchange information and personalized service.XML is a language that can be enlarged and marked, it provides a common format to the data and structured document which on the Web. As Web technology developed and wildly used, standards of information denotation and data exchange that using XML technology are adopted by more and more systems. Using the combining of XML language and database technology to carry through the management is becoming more and more important.The article designs a school credit hour course selection system that on the base of using XML technology in course selection and combining of higher education characteristic which bases on XML and ASP. The system is according with the fact that both teaching resources shortage and students origin complex, which can satisfy the requirement of school course selection management. Still using largely XML technology in the system has enriched the system B/S function.In this system research and design, firstly, the article analyses the organization structure and the functional structure of course selection, and on this base, presenting a business model, then analyzing data according to the model and then obtain the whole business model of course selection.It is a complicate process, not only to consider some restrictions on the conditions, but also need to solve an essential problem, namely the dispassion. If the problem doesn't been solved, well then the students who enter the system early will get the course he wants, and the latter may be have to choose the course he does not favorite. This certainly will lead to an out-of-order complexion that students dispute classes, making system huge presser and betraying the principle of dispassion and freedom of the teaching mode. This article gives a fair course selection arithmetic which is based on analysis to the course selection arithmetic that already have, which meets the requirement of dispassion.Course selection system has upper request to the aspect of capability, especially choosing function in the student choosing platform. Because in the process exists many subsequent users, so if maintenance fails, maybe the system server occur paralysis. So the capability is very important. Besides improve the capability of hardware, the software must be paid more attention. The article introduces some ways of improving software.On the concrete achievement, system adopts XML technology. Such as load page, student course selection page, and lead course conflict before judgement. The system also elucidates the applied methods in data addition, data issuance, data searching and data validate. Have a analysis on conflict and solve methods in course selection procession, bring forward some system advanced project, ease the press of server and data-base and assure the course selection activity goes efficiently.The object of this article is to actualize a point course selection management system which have the coincidence with higher education characteristication and afford reliable technology serves support for high school point system innovation, thereby lighten the manager's burden, reduce the credit hour teaching management's complex degree, at the same time provide the students a fair, reasonable, convenient choosing platform. Increasing the positivity and independence of student provide a evidence of improving teaching quality.
