基于校园网的在线学习考试系统的设计

在快速开放的系统原型中,采用软件工程技术对整个系统和数据存储结构进行分析和设计.其中对于数据库的需求分析、概念结构设计、物理结构与逻辑结构设计.评分系统通过逐一比对学生的答案与数据存储选择题状态表中的标准答案,实现了选择题的自动评分;通过搜索考生目录,检查和判断由某项操作结果所要求的文件或文件夹是否存在来实现一些基本系统在线题目的自动评分.

Design of Online Study and Examination Based on Campus Network

In this paper rules of classic software engineering were strictly obeyed in system analysis and design activities,including database analysis,conceptual structure design,physical structure and logical structure design.Rapid prototype method was adopted in the whole development process.The judging-score sub system compared each student＇s answers with the standard answers stored in data tables,and automatically gave the scores of all the students;by searching table storing user data,each student＇s scores could also be automatically gained by checking whether the required folder or file existed.
