基于Web的网上作业系统设计与实现

摘要

按照网上作业平台系统实现目标，完成了系统功能性需求分析。对文件的数据库方式存储和文件系统方式的存储进行了比较，并分析、设计了本系统的存储结构。完成了数据库概念模型设计和数据表物理模型设计，详细给出了数据库关系图。设计并实现了基于Internet的课程网上作业子系统、个人网络硬盘子系统、课程资源库共享等子系统。该系统已经应用到日常的教学管理中，并取得了不错的效果。%This paper analyzes the system functional requirements according to the goal of the online homework system, compares the storage of files in the database system with the storage of files in the file system, and designs the storage structure of the system. This paper completes the system overall functional design, the database conceptual model design and physical model design. After the technical research and analysis on the online homework system, this paper designs and implements an Internet based online course operation subsystem, personal network hard disk subsystem, curriculum sharing database subsystem. At present, the system has been applied to the daily teaching management, and achieved a good result.
