Vocational Schools Network System Design And Implementation

With the development of the reformation of college teaching, the pattern of educational management has transformed from academic year to credit. Most colleges provide a number of electives for the students to choose. Elective has become one of the most important tasks of educational management. On the other hand, as the rapid development of computer science and network, the educational information construction of the university has made great progress. Online elective has become one of the most important approaches of educational management. It has made up the weakness of traditional elective. Therefore, it's urgent that we need to build an online elective system to improve the efficiency of educational management.This paper expounds the work principle and operating mechanism of elective system based on network. In the functional term, this system has complete the basic functions like enrollment management, student management, electives management. In addition, to make the access management more flexible, we adopt RBAC to manage the authorities. In the NOT-functional term, we made system architecture, construction cycle and code reuse into consideration, and decided to use the popular J2EE architecture Struts+Spring+Hibernate. With this architecture, we can not only improve the modifiability, achieve high degree code reuse and layered decoupling, but also improve the efficiency of development.The study of this issue mainly aims on solving the traditional problems of online elective system, improving the quality and efficiency of educational management, push the study of computer science especially network forward, and made elective work more scientific and standardization.
