目前多数学校的作业管理都还停留在比较原始的手工阶段，作业批改信息主要依靠师生间口头传达，作业管理效率较低，容易出错等。因此，建立一个高效完善的作业管理系统来解决这些问题十分必要。

本文以实际运用为开发背景，运用软件工程原理和开发方法，采用JSP技术构建一个基于B/S模式的作业发布和管理系统的过程，以期改变过去传统的学生递交作业，老师批改作业的方式，让学生递交作业更加灵活，同时减轻老师繁重的工作量。系统采用模块化思想应用DREAMWEAVER来开发完成。整个开发过程首先对系统进行需求分析，得出系统主要功能，数据流图及数据字典。接着对系统进行总体设计和详细设计。总体设计主要包括系统功能设计，系统总体结构设计，系统数据结构设计和系统安全设计等；详细设计主要包括系统数据库访问的实现，主要功能模块的具体实现，模块实现关键代码等。最后对系统进行了功能测试，并对测试结果进行了分析总结，得出系统的不足及需要改进的地方，为以后的系统维护提供了方便，同时也为今后开发类似系统提供了借鉴和帮助。

本系统的开发使学生和老师的沟通更加方便快捷，同时也促使学校的作业管理变的更加系统化、有序化。系统界面较友好，易于操作。

Abstract

Most of schools now operating management are still at primitive stage hand, job correcting information between teachers and students rely mainly on oral communication, operations management and less efficient, easy to make mistakes and so on. Therefore, the establishment of a highly efficient and robust job management system to address these issues is necessary.

In this paper, the background for the development of practical application, using software engineering principles, and development methodology, using JSP technology to build one based on B / S mode of operation the process of publishing and management system, with a view to changing the traditional students submit homework, the teacher correcting homework approach more flexibility for students to submit their work, while reducing teacher workload. The modular thinking for developing complete applications DREAMWEAVER. First of all, the whole development process the system needs analysis, the main function of drawn system, data flow diagrams and data dictionary. Then the system design and detailed design. Design features include system design, system architecture design, system design and system security data structure design; detailed design of the database includes access to the realization of the concrete realization of main modules, module key code. Finally, the system functional test, and test results were analyzed and summarized, derived system deficiencies and areas for improvement for the future maintenance of the system provides a convenient, but

also for the future development of similar systems provide reference and assistance.

The development of this system so that students and teachers to communicate faster and more convenient, but also facilitate the operation of the school administration become more systematic and orderly. System interface more friendly and easy to operate.

Key words：B / S; operations management; systematic J
