基于COM技术的通用题库系统的研究与实现

Research and implementation of general item bank system based on COM technique

分析了COM技术,研究并实现了一个通用题库系统,该系统包括命题模块、组卷模块、考试模块、阅卷模块、成绩管理模块,每个模块做成一个COM组件,介绍了数据库的设计,提出了改进型的遗传算法组卷,利用该算法进行组卷,收敛快,效率高,能组出满意的试卷,同时对考试模块、阅卷模块的设计等关键技术进行了探讨。

COM technique is analyzed and a general item bank system is researched and implemented, which contains proposition module, generating paper module, examination module, reading paper module and managing score module. Each module is designed with one COM component and design of database is introduced, genetic algorithm that can improve generating paper＇s speed is improved and convergence rapidly and satisfy users＇ needs is put forward, meanwhile key technologies of examination module and reading paper module is explored.
