教师综合业绩评价系统的设计与实现

Design and implementation of a teacher's synthesizing grade evaluating system

本系统基于J2EE Web开发技术,以填补我校信息化建设上的空白为目的,采用了目前较为流行的N层结构的架构设计方法,并以Access为数据库,实现了用户管理、数据申报和数据审核、决策树生成、业绩评定管理等6大功能模块。开发过程中采用ID3算法形成决策树,使用基于角色的访问控制技术(RBAC)对用户权限进行限制,采用随机函数对Access数据库进行加密。本系统严格按软件工程的开发顺序,逐步实现系统的核心功能。本系统的实现是对我校教学和科研工作的又一次促进。

This system is designed to fill the gaps in the information construction of our school by using the J2EE Web develop technique. And it is constructed using the method of N-Layer structure ,which is a widely used design pattern. This system is using Access as its database, and it implements 6 modules including user management, data update and audi4 decision tree creating, grade evaluation management. This system uses the ID3 algorithm to create decision tree, and uses the role-based access control technique （RBAC） to manage user＇s authority. The Access database is encrypted by random function. The develop- ment strictly follows the sequence of software engineering, and the core function is implemented step by step. The implementation of this system is a big steo--forward of our school＇s teaching and researching causes.
