The Design And Implementation Of University Employment Information Management System

The21st century is an era of information, and the information techniques havepenetrated into all industries. With the rapid development of hardware and software,Internet has been generally applied, and has become the most effective approach ofinformation release.As the economy and culture is growing fast in China, the competition in allindustries is more and more severe. As education bases of talents, the colleges anduniversities take it as the main task of their employment guide work to help bothgraduates and employers find the resources that they need. Having worked at theEmployment Guidance Center of ARFT for years, the author obtained a profoundcomprehension of the employment guidance and its informationization in colleges.Combing with his many years’ work experience and the problems that he found duringwork, the author develops the Employment Information Administration System forARFT Students, in which the B/S Architecture was adopted.This thesis thoroughly and completely elaborates the whole process of thedevelopment, including requirement analysis, system design and the segments of theimplement, investigates the critical methods and steps in the analysis, and brieflydiscusses the relevant techniques used in the development.During the design of the system, the author concludes the experiences and lessonsfrom his work, uses the domestic and foreign experiences as a reference, combines withthe ARFT’s characteristics, designs the functional structures of the whole system, andorganizes the overall procedure. According to the categories of customers, the system isdivided into four functional modules: Backstage Administration, Students’ Information,Employers’ Units, and Information Release.In addition, this thesis briefly introduces the techniques, such as ASP.NET, C#andSQL Server2000, which are adopted in the development of the system. TheMicrosoft.NET3-tier Architecture is used in the development.CLIENT/SERVER used to be popularly applied in the development. Usually, theprogram logic is distributed at both the CLIENT and SERVER; the CLIENT sends access request from the data resource, and the SERVER sends the results back to theCLIENT. However, the CLIENT/SERVER has many problems. For example, when theclients suddenly increase, the performance of the SERVER would greatly weakenbecause of the overweight loads; once the application demand changes, both theCLIENT and SERVER need to be modified, making the maintenance and upgrade quiteinconvenient; the transmission of great amount of data would increase the loads ofInternet, and so on. And the Microsoft.NET3-tier Architecture, comparatively, is ofmany advantages to the implementation: the developer could focus on only one of thetier; the implementation of the original tier could be easily replaced by that of the newtier; the dependence among tiers could be reduced; the system could be easilystandardized; and the logic of different tiers could be simply repeated.
